Whenever you feel like you have lost yourself and have forgotten your goals, please read this quote. It will guide you through rough time.

"Just pick a goal, a goal you truly want to achieve, and take a clear-eyed look at your weaknesses--not so you'll feel less confident, but so you can determine exactly what you need to work on.

Then get to work. Celebrate small successes. Analyze your weaknesses.
Keep going.
As you gain skill, you'll also gain a feeling of genuine confidence, one that can never be taken away--because you've earned it."
