Don't dream a dream, live a dream and let reality sleep. We are born with our eyes closed and our mouths open, and we spend our whole lives trying to reverse that mistake of nature. Our greatest glory is not in never failing, but in rising up every time we fail. The climb upwards will be easier if you take others with you. Discoveries are made by not following instructions.
Business is like riding a bicycle.
Either you keep moving or you fall down. He that never changes his opinions, never corrects his mistakes, will never be wiser tomorrow than he is today. To avoid criticism, do nothing, say nothing, be nothing. The whole point of getting things done is knowing what to leave undone. If you don't invest very much, then defeat doesn't hurt very much and winning is not very exciting.
