You’re not starting over, you are starting from experience.Have you ever failed, only to try again and succeed? What did you do differently?Sometimes it can feel hopeless, what’s the point trying again? The difference is the second time you try it you have already learned one way that you will not succeed. So you know not to do that again.When you get frustrated because you can’t complete a task , it’s important to remember that every time you fail you learn. Every time you are challenged, your knowledge increases as does your chance of success. Knowledge is power only when it is used, you may know something but that is useless until you put it into action.There is no failure there is only feedback. Look and listen to your feedback, make the appropriate adjustments and try again. Use your experience as an instruction manual.
