Hey come on, you dont have to think like that. Yeah, we all die, things come to an end, but the point of that time inbetween is to have fun. Look for things you absolutely love doing, even if you dont have the skillset for it, just learn it. If youre interested in computers, look up some cool things you can do. Maybe even draw, doesnt matter if its good or not. You can learn to do these things and find out how fun it is in the long run. Watch cartoons, read books, maybe even try writing for yourself. If you dont want to be doing the same thing your entire life, go try learning new things, broaden your skillset to a permanent career and multitide of hobbies. Dont just say 'theres no point', because if you find entertainment to continue then there sure as hell is.
And you DONT have to be good, the best, or skilled, just as long as what you try provides a little fun.
