What do you want out of life?

I've been asking this question to myself for the past few hours and answers have been quite unreal as anyone would expect from a 20-year-old. I believe very few people actually know what they want and most people dabble their way through life without knowing their wants.
It is impossible to have what you want if you don’t know what you want. Just like it is impossible to achieve something if you don’t know what you are trying to achieve.
Although it's really not possible to know what you want so fast and easily but even asking this question can enable us to look for answers within ourselves.
As I start my 20s, I didn't want to make the same mistakes as my seniors made when they were young. So I've been watching some youtube videos about "Mistakes I made in my 20s".
None of them had watching porn as a mistake but I guess that's something I have to correct among other things.
