Whatever you do, avoid being so impressionable because we all fail from time to time.
Yes, you'll look like you're on top of the world when you live through your highs, but the opposite shines through during your worst moments.
And no one that has ever had success in their life should ever come across as disheveled. Everyone fails at some point, but it's our exteriors that show the true results. It's all within our own self-confidence.
Keep smiling. Express yourself like you're always succeeding. Reality might just follow suit.
