I never lose or fail.
Now, some of you might be thinking to yourself that that is an arrogant statement.
Let me add some context to it and take a second to think about that statement.
If you win or complete a task successfully, you won. You can move on to the next task.
If you lose, fail or make a mistake, you learn how to NOT do it next time.
Overall, you should always be learning and growing; win or lose.
It all comes down to mindset or how you think, and perspective.
Also, observe others, especially ones that are at the level you want to be. Learn from their wins and losses.
Always be learning. When you learn, you grow.
