Even for hard working, u need luck. People willing for hard working (and they may capable too) if no luck, can not utilize their tanlent. Eauta garib le jati sukai mehenat garera pade pani unless he is lucky to get scholorship, he can not become doctor or engineer (that's what usually it is). If u are hard working, your level will be different than lazy guys, but still u need luck among the hard working guys.
