1. When you can't hold on any longer, you can say to yourself "I'm so tired". Never admit in your heart that "I can't do it."

2. Reality will tell you that if you don’t work hard, you will be trampled to death by life. No need to make any excuses, having nothing is the reason to fight.

3. All success comes from unremitting efforts and running; all happiness comes from ordinary struggle and persistence.

4. God will not treat those who work hard, nor will he sympathize with those who are fake and diligent. Time and persistence will tell you how hard you work.
