The best thing you can do is fall in love. My life has been changed by falling in love.
When you fall in love you recognise you're not the most important person in the world, and your focus becomes another person.
The greatest poverty one can have is to be poor in one's heart and for falling in love, he is truly happy. He discovers purpose.
For me happiness occurs arbitrarily: a moment of eye contact on a bus, where all at once you fall in love; or a frozen second in a park where it's enough that there are trees in the world.
