We have a tendency of dreaming about greatness. I want to become a professional football player, or maybe you want to be a world-known piano player? It is nice to dream and you must have a dream to start with, but dreaming is not enough, and the world is full of day-dreamers who get nothing done. So, what is needed for change to happen? For many, what's needed is a good kick in the butt (or pants as Baltasar Gracian says), because that is something they can feel, understand, and make them wake up to the reality we live in.

It might not feel good, but if you want to get somewhere, you might need that kick, even though it is painful. Unless you make changes, you will stand still (or maybe get worse), but if you make some changes to your life, it might end up with you actually moving forward and getting better!
It might be that you need to be the foot kicking someone else in the butt as well, but before kicking others, start with yourself!
