Is a very broad question I know. But I realized that aside the things that liked as a kid (videogames and listening music) I gave up on everything else or failed in other things. I gave up on going to the gym, gave up trying to learn how to play a guitar, i gave up on having a YouTube channel, if I fail the theory exam of my driving licence I think I won’t try again, shit I gave up on having a social life… And so on. Is that normal in your opinion?
Just my opinion, but I’d say it’s okay to give up on many, even most things you try, but not all of them. In other words, go and try new things, it’s the only way you’ll learn what you enjoy and what you’re good at. And then stick to a select few of them.
There are also a few tips to be given on how to stay engaged with a subject. One of them: don’t stress it too hard. With something that’s meant to be pleasant, don’t push yourself to perfection until it becomes a chore. Also, if you want to achieve a more distant goal, it helps to find something to keep you going (look into how Duolingo, the language learning app, keeps people engaged).
Funnily enough I gave up on Duolingo. Erased that app after 2 months.
