The bigger the risk, the bigger the gain. If anybody is afraid of losing then put the money in a bank or in a vault no risk no gain. Take the risk if you succeed you will be happy if you lose you will become wise. it's a win win situation. But offcourse it defends on how you absorb the situation.
Precisely the more you are brave enough to take the risk the more you have chances to win even in business sometimes you will not succeed but every fall you should knew how to stand again angd give your self a try..There is no harm on trying just make sure you can handle the outcome.
