Everyone wants to happen good things in his life, no one prays to have a bad accident or unwanted traumas in life But nature has rules and you can not deviate from those rules. Nature wants to teach you how life works and you need to be ready for that learning process.
Failures and mishaps are part of that learning process, but why not everyone concludes a lesson from his failures and does better next time? This is the difference between a successful and failed person. sone people learn from their failures and take it as a life experience which will help them to shine next time.
Failures are part of life and they happen with everyone it depends on how much you learn from them and then does right in the next turn. Every great learn from his problems and wrong time
They know if this thing or method is not working it does not mean they are not capable to achieve their goal they just need to change their tactic, not their strategy to achieve their goal. Your eyes should be on your goal not on yours.
