Every decision you make in the business world has some sort of risk attached to it. If you are not prepared to take risks, you should not be an entrepreneur or business man/ woman.
Not all risks are good so try as much as possible to take CALCULATED RISK because in the long run that will reduce the negatives and increase positive outcomes.
However, bear in mind that some risks even carefully calculated ones will fail. Instead of ignoring this fact, accept it. Accept the possibility of failure. When you do fail- pick yourself up, learn from your mistakes and move on.
Most people are pessimists by nature so they fix their minds only on negative possibilities or give risks an unrealistic probability of failure. But most successful entrepreneurs will tell you they got to where they are because they were willing to take risks no one else was.
Here are some tips that can help you to take calculated risk:
1) THINK IT THROUGH
Evaluate the risk level of each opportunity you identify. Weigh the pros and cons of the opportunity, its potential for success and what you could lose should it fail. But, don't overanalyze it because as imperfect humans we don't have all the answers.

2) LISTEN TO YOUR INTUITION
There is no perfection in risk taking so just follow your instinct sometimes. There comes a time when you have to jump.

3) KNOW HOW MUCH YOU CAN AFFORD TO LOSE AND WORK WITHIN THAT LIMIT
In most cases you will need to invest some of your personal capital into a new or growing business but don't invest more than you can afford to lose.
You can decide to start small to test the water and gain confidence.

4) ACCEPT THE POSSIBILITY OF FAILURE
When you do fail, learn from your mistakes and continue moving forward.
