The best way to chear yourself up is to try to cheer somebody else up. It knows it must outrun the fastest lion or it will be killed. Every morning in Africa, a lion wakes up. It knows it must run faster than the slowest gazelle, or it will starve. It doesn't matter whether you are a lion or a gazelle - when the sun comes up, you'd better be running.
Action has magic, grace and power in it.
I love the man that can smile in trouble, that can gather strength from distress and grow brave by reflection. It is not the critic who counts, not the man who points out how the strong man stumbled, or where the doer of deeds could have done them better. Standing on the starting line, we're all cowards. Your biggest challenge isn't someone else. You just push harder.
