Are you feeling stuck? Reconnect with why you are doing what you are doing. Maybe things have changed, and your why doesn't matter to you anymore. Perhaps you need to find a new purpose to motivate you.
Remember you are never a loser until you quit trying. Keep trying, you got this!
Failure is not the opposite of success, it's part of the process of success. You won't have success if you have not failure.
Don't limit the challenges you face. Allways try to challenge your limits.
