Lord Jesus is a living example how one has to suffer in this material world simply for the matter of preaching the message of God. In Bhagavatam also there is another example like Lord Jesus. He is Prahlada Maharaja a boy of five years old but because he was a great devotee of God and preaching the message of God among his little class mates, his atheist father tried to kill him. So the atheist class of men are always inimical to the devotees of God even though such devotee happens to be the atheist's son like Prahlada.
I proposed for starting the restaurant with a view that you may become one of richest family in America. One can become rich only by trying his luck in business. It is not possible by serving other. One should have independent source of income that is possible only if one is engaged in business or in land lordship.
