Its true some of the most success people in the world are the biggest risk takers I'm not talking about sticking your mortgage on red in a casino, although maybe, lets face it 50/50 split. hmmmm
The other factor that is common in the successful is when it all goes tits up. Look at business people that have been made bankrupt and still come back. Alan sugar pulled honself back from financial ruin.
Take the risk but know what steps to take if it doesn't work out.
