There is a great number of people coming into our lives(well, provided you're not sitting on your sofa at home all day long ). Some of these people attract us, others not. Anyway, the decision should be made according to your inner feelings.
Decisions, made rationally or should I say with you "head" often make us unhappy in the first place. We betray ourselves. Sometimes you look at a man and realise that there is some kind of connection between you. You simply want to talk to him/her, in spite of the fact that there are thousands of people like him/her around you. However, only this person can come closer to you, you allow it to happen and there is no rational explanation to this, you let your intuition guide you and if you live in harmony with your emotions, then all reasons why you "can't do" become secondary, it becomes irrelevent and absolutely non-essential. You simply come closer and closer, becoming intimate despite the rules or public opinions.
The single thing that can hinder you at this moment is your head(mind/ego), stealing happiness and intimacy from you, robbing you. When you start thinking and analyzing both of you.
Everything is quite simple, either it's your kind of person or not. It's dumb trying to please, it's stupid to impose yourself. All you'll got is pain just because you were not who you really are, you see? You were not authentic and now it's a payback time. Simply because you had to wear a mask instead of implementing your desires and doing what you really love.
Sometimes it happens that you meet someone successful, he's handsome, intelligent, the life and soul of the party, but there is no connection between you. Cease the conversation. Nothing's good going to happen. Sometimes you talk to a girl. She's a model, very pretty, but...there's no connection. Cease to converse. You won't like sex without emotions, it's utterly insipid. Learn to let go. Don't betray your soul. If you let your feelings guide you, finally it will lead you to close friendship, beautiful romans and interesting events.
Happiness is all about inner connection. That's what they mean saying "listen to your heart". Try to interact without it - and you will end up in your inner prison. You can't escape from yourself, running away is pointless. Deprived of freedom. Afraid of being alone and abandoned? Being "too picky" asking "too much"? The desire to impose oneself and to please someone occurs only from the position of neediness.
What should we do then? Well, simply to get more acquantances, talking more to people, going out of our comfort zone, because everything we want is outside of that zone. If you do that, you will meet wonderful like-minded people. And when your life is full of abundance, full of friends, then letting go others would be simple.
