Nobody is your enemy.
Your enemy is your ego, your lack of focus, your jealousy, your procrastination, the gaps in your knowledge, your inability to believe you deserve more, your excuses, your self-doubt, and your fear. That's the only enemy to focus on beating next year.
The only way to never lose is to never try.
Everyone who has never dared to step into the arena is undefeated.
Ironically, these people are always the loudest and the first to critique.
