First, realize that "all your life" is not really that long if you're 20 years old. You've got a long ways to go and you will absolutely change over time, usually without even noticing it. You're in college right now, don't sweat it like this is going to be your whole life.

Second, I would suggest getting some different kinds of hobbies. Do a bunch of different kinds of things. One benefit of this is that if you know ahead of time you won't be good at them so it's easier to not hang your self worth on them. You'll also meet different kinds of people who aren't just CS people doing projects you can judge them on. Doing lots of different things also makes you a more interesting person.

Third, in terms of your programming; find more joy in the process and the trees instead of investing everything in the forest of The Project. If something turns out worse than you thought but you learned a lot, great.
