7. Drugs and being "hard." Teens--you want to be the dude who's "on all da drugz" and is a "felon" Twenties--you don't want to "still" be that dude, but you still want to "have stories" about "partying too hard" and "getting into trouble" when you were younger Thirties--You realize that all of those things are stupid to brag about. None of that is remotely cool anymore and no one cares.

8. Thinking that you're a better/smarter person if you attend a specific university. I went to school for free and have had a great career. At 17 I was embarrassed by going to a state school but after I started my real world life, I realized it didn't matter at all!

9. GCSEs. When I was 15 they were the biggest deal. Meaning no disrespect to anyone who stopped school at 16, but I can’t remember the last time anyone asked me for my grades.

10. Drinking booze on the sly. Sneaking it past your parents. Instead of a rebellious youth, you become the closest alcoholic.

11. Worrying whether your parents will approve of any given personal choice you make.
