Do not get so concerned with making a living that you forget to make a life.
I don't believe in praying to win.
Losing does not make you a failure; it is when you blame someone for losing when you become a failure
Don't mistake activity with achievement.
If pursuing material things becomes your only goal, you will fail in so many ways. Besides, in time all material things go away.
You never fail if you know in your heart that you did the best of which you are capable. I did my best. That is all I could do. Are you going to make mistakes? Of course. But it is not failure if you make the full effort.
