"Nothing worthwhile comes easily. Work, continuous work and hard work, is the only way to accomplish results that last." Hamilton Holt
Yes, good things come to those who persevere. Those things we get as a result of hardwork is even sweeter than those which had been handed out free. We even give more effort on it after because we don't want to lose all those hard work we put on it during those trying times.
Businessmen tend to work harder, not just physically but mentally, than ever after they have built their businesses because continuous hardwork is the only way to accomplish results that last.
Nothing worthwhile comes easily indeed!
