What is your best advice for an 18-year old?

A millionaire at the age of 30 is far more better than a billionaire at the age of 90. Start planning!
Don’t wake up accidentally. Wake up with a purpose!
No matter how many times she says , “ I love you,” she’ll leave you if you still remain incapable, broke, incompetent.
You were chatting with her for five years , night and day. On the other hand, there was this guy who was using those 5 years doing something productive. Human Being changes. One day, she became fed up with you and left you for the other guy. Now, the other guy has a job and a girl and you have neither.
Adopt the Carnegie Philosophy of life — Learn, Earn , Donate.
The Greatest Teacher lies in you. Teach yourself as much as you can first before asking for help.
You have only one life. Do whatever you wanna do provided it doesn't hurt your self esteem. If you want to sing, go grab the mic and lit up the stage. If you wanna become a programmer, jam your lappy. If you wanna learn parkour, go and break some bones outside :-(). Enjoy!
Never fake maturity/depression on Social Media.
Never run back to your ex even if she/he is the last person on earth. An ex is an ex for a reason.
Never stalk your ex on FB , Insta. I repeat , “Never”.
Never let Bf, Gf, Crush compromise your studies. Take frequent breaths whenever your anxiety level goes up!
If you have a Bf/Gf , commit to her 110 %. Don’t use him/her as your target practice. If you can’t commit, quit him/her and move on!
Every love story begins with : “He/She is different,” and ends with : “He/She is like anybody else.”
College degree is very important. Don’t drop out of college unless you have enough calculated risks. Will you be selling pani puri on the roadside when you can’t become the next Bill Gates or Elon Musk?
Never chat with your crush/bf/gf while studying. Go ahead if you dare!
Stop posting your shitty hearbroken stories on your social media handles . No one gives a damn about you.
Your number of Instagram followers or PUBG kills has no place in your CV.
Stop posting screenshots of your intimate chats with your bf/gf/crush whatever. Who the fuck wants to know about your private life? Keep private life private.
A Whatsapp Status lasts for only 24 hours.
Don’t become a philosopher on Facebook.
Never use profanity while chatting with an elder/junior/bf/gf/crush/ female friends even though you don't have strong vocabulary to express yourself. Mild swearing is okay! :-)
Stop removing your Whatsapp DP/deactivating your Fb,Insta whenever you have an emotional setback. Learn to be strong.
At 18, your hormones must be kicking up. Keep the bed pure until you’re married.
Start planning how you can make yourself self dependent by the age of 25.
Never trust anyone in this Golden Era of Screenshots.
Never share your complete private life with strangers.
Friends can turn into foes and foes can turn into friends. You don’t know what happens in the very next moment!
Stop arguing about BJP and Congress. It’s better to debate on Area 51 rather than politics.
Always draw a fine boundary while chatting with female friends . You may be a victim next!
Make your own bed and breakfast.
Pornography is just an illusion.
Instead of impressing others with your filtered photos on Insta, start impressing yourself in front of the mirror.
Turn your smartphone into a learning machine.
Never waste time. A second less does not make an hour. Time is everything , everything is time.
Whenever there is a conflict between the heart and the brain, go with the heart. The end result will be a satifying one. Believe me!
Be action oriented. You’ve made enough plans, enough time tables , pasted enough motivational quotes on your wall, watched enough motivational videos, films etc, but still you haven’t changed! Why??!
No one will value you until you’re rich or successful.
Never give advice to your friends unless when demanded. You may be in trouble in the end.
The World is Fire and Blood. No one gives a damn about you. No one!
PUBG and Mobile Legends are the greatest shit the entertainment industry has presented to the youth.
