Your Successes give you Confidence; your Failures give you Wisdom; a little bit of Luck helps as well.
No matter what you are undertaking, you need Confidence and Wisdom to be successful. Confidence without Wisdom will lead you to make stupid mistakes. Wisdom without Confidence leads to a life of frustration. As well, good and bad Luck can determine the degree of Success or Failure.
I have made $1,000,000 five times my life and lost it five times. Many would call me unlucky. I put it down mainly to poor timing (aka Luck) and lack of Wisdom (aka stupidity). Fortunately I’ve had the Confidence to make that million dollars back four times, (aka Creativity and Perseverance) and am presently starting on my fifth million.
I have gone bankrupt three times. Many people would call me a bad businessman and they would be correct. I’d rather call it naivety and a lack of Wisdom in the area of business management.
Timing and Luck tend to go together. If you have the Wisdom to understand the herd mentality of sheeple, recognize the cyclic nature of world events, and the Confidence to make major decisions, you can frequently foretell when the bubble is about to burst (aka buy low and sell high).
There is little to be said positively about old age except hopefully attaining Wisdom and the Confidence to trust your decisions.
