Life = luck
Newton started to think about gravity because an apple had fallen on his crazy head. Einstein had worked in a post office for years before someone gave him some attention. So yeah, we need to work hard, but nothing is guaranteed in any case. Soooo, relax sometimes.
How long can people wait, and how much do they have to endure, to find happiness and realize their dreams. Most of us know, that in order to achieve something, we must work hard and be patient.
