Want to get into construction but I have zero experience

Hello everyone. I’m a 21 year old who’s interested in working in construction. I really want to learn about construction because I know literally nothing about it. I want to know how to build and repair things when I’m older and have my own home, I find it very respectable that you guys have the knowledge to raise houses and maintain them as well. However, I’m a dumbass and have zero experience or knowledge in construction. Because of this I’m really nervous and don’t really know how/where to start because I’m quite the slow learner and I definitely don’t wanna get fired or in trouble because of my lack of skills. It also doesn’t help that I’m Mexican lol.

Has anyone ever been in the same boat as me? I’m thinking about going nuts out balls deep and just getting a job and whatever site accepts me but I’m also thinking about starting off with landscaping. Any tips?
