I appreciate what Jack Ma said: "Are you really tired? It's right to be tired, comfort is for the dead! Suffering is life, tiredness is work, change is fate, endurance is experience, tolerance is wisdom, tranquility is self-cultivation, giving up is getting, and doing is having. If you feel that you are having a hard time at this moment, tell yourself: the easy way is downhill, hold on, because you are going uphill."
