I am no expert at all though I had some observations with my very little experience. I concluded 2 things:

  1. Deep inside you are emotionally detached.
    Getting attached to someone is asking to get hurt. I don't mean you should act like you have no emotion but just don't get too attached to any girl.

  2. Keep momentum.
    This goes well with 1 just as 1 goes well with 2. Once you stop you will slowly lose your "game". That girl didn't work out? Time for the next one. New experience, new adventure. No time to sit in your couch and get sad about it not working out. You can't change the past but you can change the future. Life is short, enjoy it.

Thoughts?
