The chance of making mistakes will be much greater if someone learns not using the right knowledge and that is why we need to learn from the right person. There are people who learn autodidactically and they master many things but not everyone can do the same thing because they talk about different levels of intelligence. Learning from other people's mistakes sometimes does not provide real experience because they only tell stories in general, but if we learn from our own mistakes we know better where to fix them.

Experience will be the best teacher if people want to improve and successful people have failed more than once. Increase your knowledge and evaluate each failure to achieve the desired success because the most important thing is to be consistent and continue to try to improve from previous mistakes.
