The magic word which makes the life much easier once you learn it:NO. Hahaha very smart girl, I also learned quite late in life to say no. I also noticed that it lowered my energy to always say yes. And it draws the wrong people, the ones who use others who can't say no to get their way.
Gossip and caring about what other people do is a habit of bored, hobby-less individuals. If somebody is happy with their life and has goals, there is no time to gossip or to pay attention to what others do. I also stay away from such people as their only joy is to speak badly about others behind their back. It is only a matter of time until those kind of people will gossip me. So being an introvert makes you super selective and picky. And this is good if you want to stay away from bad influences
I think that you do an excellent job if you focus solely on you and what you have to accomplish in life. It is much more useful as we become better people when we work on ourselves
