I am in good shape these two days, and I have a good chance to be appreciated by my boss/teacher. Don't be stingy with your own strength. If you can finish your work/study by working overtime, you can finish it at one go.
Dreaming that there are some tender pumpkins in the field, I don't want to give others good or ill luck speculation:
With a solid foundation, the situation can be slightly stable and there will be temporary success, but unless perseverance is strong and lasting, it is difficult to make great progress, physical and mental fatigue, and it is easy to have diseases such as brain lung disease. Good luck and bad luck meet.
