The bottom line is that we are all experts on our own personal happiness, no one else holds the key or the answers to it. I would like to end this column by sharing a statement by Robert Louis Stevenson, it is the best advice on the subject that I have found. The trick is to make the laughter outweigh the tears. Don't take yourself too seriously. Don't borrow trouble.
Imaginary things are harder to bear than the actual ones.
Since hate poisons the soul, do not cherish enmities, grudges. Don't hold post-mortems. Don't spend your life brooding over sorrow and mistakes. Don't be one who never gets over things. Do what you can for those less fortunate than yourself.
