You have the mission
When it feels like everything is crashing and burning. Don't hide. You have never been closer to the next level. It happens fast when it happens. The signs of progress are no signs of progress. You just to stay in the ring, take punch after punch, and get up over and over again.
Going to bed each night feeling like you didn't get anything done is normal. When you want to be the best. You always feel behind. There's always something to execute, improve, and learn. Let this feeling burn inside of you. Don't water it down. Ignite it.
Learn to love the fire. It's what makes you, you. When it feels like it can't get any worse. Smile. It's about to have never been better. You have the most valuable thing in the world. A mission.
