It is very difficult to be like the other guy, to be ordinary. Mediocrity takes a great deal of energy. But to be ourselves is very easy. You don't have to do a thing.
The freedom from something is not true freedom. The freedom to do anything you want to do is also not the freedom I am talking about. My vision of freedom is to be yourself.
It is very important to generate a good attitude, a good heart, as much as possible. From this, happiness in both the short term and the long term for both yourself and others will come.
