Just turned 30, thought to share things which I have experienced till now in order to help younger people.

Hey guys, this is going to be long post but I'm optimistic it will help many people.
I will share my experiences in categories Education, Job, Relationship, Marriage, Health, Wealth, Family.

Education: I'm one on those who got below 60% in 12th and I was never targeting any govt. job as I have seen my father struggling with financial condition before 6th pay. I was in state govt. school from 9th standard because even after costly schools you have to go to coaching. It was govt. school so no 75% attendance rule was there. How did I utilize this time? 1. I went to English classes, because I was going in state specific language school, and I was really good understanding English specially speaking. 2. I got computer in 10th stander (gift from papa) and started exploring both software and hardware part.
My interest was always on logical things like trying to understand how things work not just read and write in exam.
I have told I had interest in computer, so I wanted to do Computer science engg. but I was not able to qualify any exam so I can get govt. college, and my father was not having enough money to allow me private collage. My grandmother gave her saved money from pension for my admission. After joining college things changed so much speaking English was other thing my writing exam in English was another thing so I was failed in 2 exams in 1st sem. My friends were really good and supportive, and I improved a lot in writing as well everything was good in the end on 2nd sem. now it was time to add skills, I started reading books of Networking, Operating system, algo etc. helped me so much so understand things deeply and parallelly started coding in 'C'.
So, Student reading this please focus on your skills don't be a book worm, I'm not saying do not score in exam what I'm saying is please make sure whatever you study you understand that and maximize doing practical.

Job: I told I was below 60% in 12th so only BPO companies were shortlisting me, so I prepared PG-Diploma and went to Bangalore. After 23 interviews in total, I had 3 offers it was not really great offers, but I got good start. I was lucky I would say I got job at 22. My roommates from collage joined coaching for GATE to target PSU govt. jobs. My opinion is you only can identify what you like most and if you develop skills and focus on your interest you are going to enjoy your job.
So, people who are waiting/preparing for job please set your timelines because be practical age is not just a number.

Relationship: This part never worked out for me on 1st I got cheated and 2nd her parents did not agree. I will say everything is important in life even heartbreak because you learn a lot about yourself and the people. Worst part for me was I started consuming alcohol and it kept on increasing. I will say if someone left you never hate them just forgive them that's the only way I found to get out of it and yes, these things take time so do not be alone ever in these situations and keep yourself busy as much possible things pass on. If your relation is going well that's great but always be prepared emotionally for worst because at the end, we all are humans and things can go wrong anytime.
Advice here is never treat your girlfriend/boyfriend above your family, your mother and father want best for you most of the time your parent's intensions are only for your own good.

Marriage: Got married to girl my parent's selected, we are from same stream, and she is also in job and supporting her family. Very simple girl, we talked and liked each other, and marriage was fixed. I will say I'm very lucky person because life is beautiful when you have a partner who supports you.
We rented in 1BHK and manage everything by our own means no house helps for anything like she cooks so I do dishes, she does laundry I put cloths to dry. She is really hardworking and continue to improve her skills. And best part guys I left my alcohol addiction. Marriage is big decision of life and very personal as well.
So, my advice will get married when you are ready financially and mentally both do not just get married out of lust or sex because life partner your better half is leaving her home, her everything for you. You have to respect her and support her as well.

Health: Very crucial part which I ignored but when I got like 28 things started showing like my joints pain when I use Indian style toilets, I got jaundice then I got to know how much damage alcohol did to liver as well my BP was on higher side because I used to eat a lot of chips and packed salty snacks.
I request please ignore packet foods of any brand as much you can, I sip tea made of jaggery powder and only on home, if I go out to eat, I eat simple Indian food and avoiding Maida as much possible.
I started running in morning, doing yoga, doing fast once a week eating fruits and dry fruits in the Morring. If I want to eat anything I ask my wife to make it, and she is very happy to cook for me. Homemade food and good habits made me recover from all those deceases in around 6 months and I lost around 7 KG as well.
So, my advice here will be that eat healthy and home cooked food and if that is not possible learn cooking, my wife thought me many things and now I can cook food really well. Soft drink, fast food, oily food, packed food are worst for your health.
Do running as much possible because those steps count on your smart watch are useless believe me running is best. Leave alcohol/smoking as soon possible OR these habits will hit you hard one day and you might not have enough time to reverse the effect.

Wealth: There are many reasons to spend but few to save, I learned this from my father that spend on needs.
So, I started using formula of worst-case scenario because for money anything can go wrong. I started building by emergency fund (FD, Liquid Mutual funds and in savings account), I took life insurance 20X of my salary, I took health insurance for me and wife both because insurance from your corporate do not cover everything and 1 hospital bill can eat your all savings so be prepare for life and health related issues. And funds I saved I can easily survive more than a year if we both get jobless so these funds will help us in hard time to find a job. Me and my wife both invest in different tools. Did not invested in property because not clear where we will be settling down. I did not bought car because I do not need it now, bought a Activa after more than a year of marriage. Me and my wife can buy latest flagship every year, but we don't because it's not required. That's the way we help both of our families as well in need of money.
So, my advice here will be please creating an emergency fund for worst-case scenario it depends on your choice for 6 month or more but be prepare for 6 months at least and life insurance and health insurance are best when you early in your age.

Family: We do all these things for family correct? Some people will say I do things for myself only (for different reasons) but giving time to your family is really imported. I travel twice a year to my hometown mostly in Raksha Bandhan and Diwali. I hardly discuss my work and take leave when travel, I do not opt for WFH.
I go out at least once a month me and my wife both we watch movie eat in good restaurants and I buy her something when we go out like a small earing or Kurti whatever she likes because she does not spend until I buy for her. I was lucky enough to be part of team where culture is not toxic and best manager so I can do work life balance.
So, please give time to your family scrolling short videos will not make your bonding strong but giving time and talking will.

That's it I wanted to share; I have left section of mental health and because I feel I'm not experienced enough to talk on this topic. Other people can also share in comments.
Hope you find this useful :)
