Yes. I used to all the time. Plus then I had my first child at 20 and then children became my focus. I didn't have any clue about myself. I did various things (work and mostly learning wise) and in those 10years I also had alot of therapy and went to alot of self development classes. I have alot of qualifications. It's only in the last couple of years I've been really focused on what I want and known who I am separate from my children. Obviously I still have to completely factor them into everything.
Any way I read something that helped in a book I read called "women who run with the wolves" (there was lots in there but this stuck out) "when lost in a fog pick a direction and stick to it" basically in a fog every direction eventually leads out of the fog. That book, although focused on women, is a book about not knowing your direction in life, not fitting in and uses fairy stories explaining their original state and message. It's a good book to read about life direction generally.
You're a guy, not much older than my eldest son, and unlikely to have a child placed at the centre of your purpose. It'd be providing for that child if that did happen more than day to day, moment to moment raising so your path will be different regardless.
But i think it's natural when young to feel confused. It's worth spending time alone to get to know yourself and ask yourself questions about yourself. "what do I like" "what are my dreams" "what do I want" "when and where do I feel most relaxed" Answers to these questions give an idea of the career you feel happy in, the place you'd like to live, things you'd like to achieve if you answer them truthfully.
When i was younger I thought I wanted alot of money. Wanted to go into pharmaceutical sales and studied a Chemistry degree.
If I answer questions about myself relating to that field "what do I like" - I like complimentary medicine "when do I feel relaxed" when I know I'm doing something, however small, to help people and working for a drug company feels more like helping the drug company because no doubt at points I'd have to peddle less than great drugs.
So pick a direction and stick with it. Take time to know yourself and ask yourself questions about yourself.
