I was planning and behaving according to this concept that if I focused for the time being in excelling and mastering what I'm doing derived by this passion, just only driven by the passion for doing it, money will come later, but if you focus your effort only because of the money now, you will be short sighted and you will not reach to the same altitude. That's what I heard today about the talented football players in Africa, where this was the first advice to them.
