1. Most of the girls want to marry a guy with a package of INR 12 lacs p.a. or more.
Yes, your looks, charm, mannerisms, style, nature might help as an advantage, but the primary thing will be your package.

2. Nice guys often do finish last.
Bad guys break girls' hearts.
But girls break the heart of nice guys.
Its sad, but its true.

3.There are instances where the society will judge you just because you are a guy.
"All men are ba*tar*s."
"All men cheat."
"All men are the same."

No they aren't.
And this generalisation pisses me off too.

4. Some girls will use you just to fulfill their attention seeking tendencies.
They'll keep you on hold 
Play with your emotions, your time, your money and then you'll get to know she has a boyfriend.
Too bad!

5. Don't be blinded by hotness.
The moment you see a hot girl, your senses take a backseat.
And probably you yourself are responsible the most for the misery you put yourself into.
Keep your head firmly on your shoulders.
Be stable.
Be practical.
