Well I'm 55 and as someone who has been trying to be friendly to anyone ,I want to say I am not going to be the person I was before. Many people are not worthy of spending your time with . Let me categorize them.
People who are never content .Do everything you can for them, they are always demanding and trying to describe your powers as weakness, so even short talk with them make you feel sad and helpless.
People who can't teach you anything. Actually there are nothing and they try to make you nothing too. Instead try to make friends with someone who is superior to you ,mentally, financially or scientifically... Because they have potential that you don't have and they improve your lifestyle in many way!
Stop meeting who look weird in your opinion, they make you feel inconvenience. When you are with them you are stressed out ! Be aware you were not born to please others and if you would , you should please yourself first!
And the most important group you must avoid them definitely : Jealous Ones! But how can we recognize someone envies us ? There are some important symptoms. They mension your successes in steering way ,they are always teasing you all the time! They response your affection with revenge and devil actions. You would be surprised and ask yourself :while I've never done any bad thing to them why are they reacting this nonsense? Why do they try to present me as a bad person to other people ? Why are they so mean to me ?
You know why because they are jealous of you, even about things that you don't notice! But they are focused on every single positive aspect of your life and they trying to pull you down whatever it takes and for whatever it really doesn't matter!
Jealous people's face color change whenever they see you. Any new thing about you bothers them such as new clothes, new car ,new house ,even new humble pen ! So I recommend cut your relationship with all these people . We just live for once and we deserve to be happy and socializing with those who give us good feeling about life !
