I dream of becoming a billionaire. But I never spend sleepless nights thinking about it. I work little by little everyday to reach there.
When I was a kid, I wished that I would find a genie who would grant me wishes. But when I grew up, I learnt that, we ourselves are genie. We are the only one who can grant wishes to oneself.
If one works hard, one can achieve success. So find something you love, and work hard.
