The thing is you're young. It's a good thing you're 23, you have a whole life ahead of you. If you were 63, then you'd really be in bad shape.
I left when I was 20 and I had a lot of catching up to do.. and I did. I still attend college because I can only go part time. I will finish, and you will too. Don't be too bitter, because at least you have proof that you are intelligent and can lead an information enriched life, you're not a blind follower, you are willing to question, you are willing to learn. Your childhood is always dictated by your parents/caregiver. You've become an adult now, so it is your responsibility to make the right decisions for your life. You have plenty of time to do it!
Congratulations on not letting your mind rot, I am a firm believer in education. You will do great in life. Check back in another 23 years and let me know where you are by then!
