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.
Only one thing I expect from all of you: to be yourself, to discover your inner beauty, your purity of consciousness, your hidden splendor - and spread it to as many people as possible. People are miserable. Help them to laugh a little, to sing a little, to dance a little.
