It all depends on how you choose to live your life.

My life for significantly worse after high school but that is because I got tangled up with drugs and fucked my life up pretty hard when I was in my late teens and early twenties.

However once I found my feet and stopped fucking up, it got significantly better and I generally enjoy my life much more now than I did after high school.

Having a job you like, having a decent income, and a few really good people in your life is invaluable. Also being able to actually spend the night with your girlfriend and bang from sun up to sun set without worrying about your parents walking in is a definite plus.
