Defeat has a better insight to react better next time if you can. It should help to move on. Failure should not be a source of despair but a fresh start. Defeat is a school where truth is always more vital. The truth that is going to show you the path. Be a better person; enjoy to help people. The truth is that the most valuable things that you have are your time. If you start to listen to people, you cannot change the result. They cannot give you the things that do not have: Wisdom.
For many artists at the beginning of their career, I have noticed that they had to learn communication through their art. We are the only creatures that have to invent a language to communicate. We can use letters, shapes to share our ideas. The basics of excellent communication skills run universal through all disciplines. If you fail, there must be a good reason that you have to improve things. Without defeat, it is nearly impossible to improve. It is just a part of the process.
