A golden rule.

I’m going to share with you here an essential rule that took me years of my life to figure out, in fact it’s a basic rule, yet few respect it when it comes to dating.
In life, we are always advised to give of our selves all the time, at work, family and education.
Always make sacrifices and don’t ever give up.
Well in dating (not long term relationship), you must forget about this.
And instead change your reality to this golden rule:
Always be your first priority.
Help yourself first. Women, sometimes, can be very manipulative and will enjoy see you following them and seeking their attention, but will dump you in seconds when they want to.
I’ve seen many people suffer greatly because of this.
They keep following one woman, even if she is throwing at them tantrums and drama, then she gives them a mediocre excuse to dump them easily.
Don’t get stuck with a woman that you feel you are giving more than you should.
If she doesn’t show on several of your dates, say bye to her and dump her first.
If she ever degrades you or tries to lower your self-esteem, thank her and hit the road.
By applying this attitude to your dating life, women will know that you are a serious man and games must be avoided with you.
What's your opinion on this? I know, many have found my stuff rather strong. What's your take?
