There is no courage without fear. The way you counter fear is through preparation. Preparation gives confidence. And confidence is knowing you have what you need to succeed.
Giving up is easy. Whats hard is knowing I didn’t get anything from yesterday but I’m going to go harder today. To get up everyday and give 100% and be in the same position but mentally know you are trying and trying and trying.
You don’t need more confidence. You need more evidence. Confidence is built from repetition, not affirmation. Prove yourself to yourself enough times and arrogance will look like humility because you’ve earned what others only pretend to possess.
