The Nice Guy syndrome

Using these words, «the nice guy syndrome», it seems like a degenerative disease that's terrible to have, with grave consequences on your health.
The truth is, it's not a disease, but it could kill you!!!
Yes, it could.
It could make you infertile. (I hope you see my point now)
It can, and it will, cause you so much pain and loneliness. Trust, I've been there and I wish it for no one.
So, what are the symptoms?
Well, they are many, but I will discuss only five of them here:

Paying too much attention to others and forgetting yourself.
Trying to please other people, especially women.
Always finding fault on others and never on you.
Denying change, and a deep desire to stay as you are and it's the others who should change.
Boy like thinking
In short, you aren’t the master of yourself, you live only for others , pleasing them, keeping to their expectations …
It’s definitely bad when it comes to women.
