Dear Mr. Nice Guy,

Since the dawn of time, you have been puzzled by this question: Why do good girls love bad boys? "I'm the good guy," you say. "I do nice stuff, so I am the one who deserves the girl, but why did she choose that bad boy over me?"

Well, here is my answer for you, Mr. Nice Guy. Girls don't love you for who you are. They love you for what you do for them. You put their needs in front of yours. You give them emotional support, and you are always be there for them. Ain't nothing wrong about that, of course. Doing nice to others is wonderful, but by doing that, you instill a mindset that you are lovable for what you do for them, not for who you are. You are known for your good deeds not your own merits.

Now take away those nice things you have done to them. What is left? Nothing. Without your little acts of kindness, you would be remembered for nothing at all.

I am not saying doing nice is bad. It is wonderful. Just, please don't expect people to love you for that. Repeat after me, "they love my acts."

Here is my suggestion to you, Mr. Nice Guy. If you want people to love you for who you are, you should present yourself in such a way that do not just involve doing good deeds. Less of doing nice things to please people, more of presenting your trait and personality, in other words, be yourself, show your individuality. 

Good luck!

Oh more useful information, you should listen to what experts say too.
