Your first love will likely not be your last – and that’s a very good thing. Very good.
A few good friends > lots of mediocre friends. You will be far more fulfilled with a select few people in your life that know you inside out than tons of friends who you don’t really know.
If you don’t like doing something/a certain person/your job… then you have the ability to decide whether you want to stop doing it/cut them off/quit. You are not stuck!
