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.
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.
Do you want to be a power in the world? Then be yourself. Be true to the highest within your soul and then allow yourself to be governed by no customs or conventionaliti es or arbitrary man-made rules that are not founded on principle.
