Never say you've won with girls

In dating girls, a lot of guys will have the warrior mentality.
The warrior mentality is:
Getting ready to war, going to war, kill as many as possible, wining!
Well, in dating, most guys tend to do the same.
They will prepare for a very long time, try to date as many girls as possible, impress them and wining!
This mentality will probably lead you to some success, but it certainly will lead you to a lot of troubles too.
The first one is that you are going to think that girls are like trophies you have to win as many as possible.
And the second issue is that you are definitely going to burn a lot of energy with girls trying to win them.
This is the reason why I advise guys to always have the fisher mentality.
A fisher will sit in a quiet place, throw the bait and wait.
A great guy will go where women are to meet men, be great looking and ready in his inner game and wait for the right opportunity to approach that one girl that will make all the difference.
