Jack Ma. Jack Ma said: Are you really tired? Just be tired, comfort is reserved for the dead! Suffering is life, tiredness is work, change is destiny, tolerance is experience, tolerance is wisdom, tranquility is cultivation, equanimity is gain, and doing is possession. If you feel that you are working very hard at this time, tell yourself: the easy roads are all downhill, hold on, because you are on an uphill road, and you will definitely make progress.
