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.
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.
A man can be himself only so long as he is alone; and if he does not love solitude, he will not love freedom; for it is only when he is alone that he is really free.
