Right business is big mountain in the beginning but become beautiful beach in ending

We are always surprised when we meet our friend that has a settle business in his arms. Maybe two years ago, one year ago, or maybe just three months ago, he is still same like us. An employee of company and same level or maybe lower than us. He has salary same with us. Why is he so successful now? What does he do? He worked 8 hours and do a joke like us. But during 8 hours and after 5 pm, is he do same like us? Why did he left us a thousands km? a million km? His income is not only to be double, but maybe 10 times or more than us. We just look our face in the mirror and said: why am I still here? It's our homework.......
