Yes, mistakes are the stepping stones to success because everybody knows that gambling is very risky, while gambling it is impossible to make profits because gambling is very risky. We have learned from our mistakes in order to overcome those by not gambling again and again.
Mistakes are said to be the stepping stone but most of the people are having a lot of mistakes but are still not doing anything that will help them surpass that mistake. Gambling can generate profits, it is not impossible, it is just a high of a risk near to the word impossible unless we are talking about a business.
To overcome our problems, we need to face it not avoid since we will be making more problems at our hands if we avoid it in the future.
