Trying to create my own sounds

Producing for five months now, every day for at least an hour, I've really put a lot of time and effort into this. I love what I'm doing, but I think it's time to learn how to create my own sounds from scratch. I've never learned how to make my own sounds before (always used presets) so I tried for a few hours today. It's hella fun and interesting, although it's confusing as well.

I just wanted to ask how you learned to create your own sounds? And what is the best way to do that?
