1. Wear cartoon-branded T-shirts.
We all know that Superman was a Kryptonian who could fly without wings, but surely on the other side of the calendar you just know Superman was a just a movie character after all.

2. Play loud music in your car.
Playing loud music is so cool especial if you are playing it in your first jalopy that your parents gave you, but a loud eardrums tearing music coming out from a 30-year-old’s car is not on.

3. Play video games
Playing video games can be fun for anyone, even for a 30 year old; however you can’t chase those Zombies all night long, trying to score more points than your friends instead trying studying to get ahead in your career if you have that much time.

4. Stay with your parents
Your parents liked having you around, especially as a toddle while you were looking cute in your Babygro. But when you are a 30 year old you can’t do this to your parents who are trying to hint at you that it’s time to pack your bags and get your own place.

5. Cohabit
Sharing accommodation with your partner is a good feeling. Trying to impress her by sharing a toothbrush is for college students, not for a 30-year-old.

6. Saggy Pants.
Even the famous rapper Jack Parow does not wear his pants below his bum.

7. Stalk your ex on social media
Checking your exes on Whatsapp or the status of your ex-boyfriend or ex-girlfriend on Facebook is for teenagers.

8. Have a bad credit record.
In your 30s you should invest money, think about retirement and not blow your credit card. What’s the point of having more than one credit card?

9. Party all night long
Drunk with regret and bloodshot eyes is fun for the 20 year olds.

10. Do not Procrastinate
