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.
That's what most will say, and in business, somewhat that is usually the case. However, I would add that, in this market, you should only take calculated risks rather than just purely risks hoping that it could turn out to be a gold mine where you would strike it rich. That's such an uncomfortable and unreliable premise to hold onto in this market because the avenues for losing your investment and money is so wide. Therefore, as much as you would jump in and have a leap of faith sometimes, it would be better if you would still study the background before moving in on something.
