The secret to great results is simple. You have to take risks for your purpose. Learn from mistakes and retake the risks. Those who know this secret are rarely sharing the other side of the coin, that if you risk a lot, you will often lose.
You will fail significantly more often than others around you. To achieve a big victory, you will have to live through 100 serious defeats. And the skill to get up after falling, to recover your broken wing or coming back to play after hitting a brick wall becomes crucial.
Not only that, but most importantly, you should learn to analyze your failures, learn from them, and train your ability to benefit from each defeat. Without these skills, any risk becomes worthless and leads to nothing but pain.
Another question for you to ponder:
What is your purpose that makes taking those severe risks worthwile?
