In my youth, I was considered a bright and diligent student. How did I accomplish this? I tricked my yetzer hara.
Other children had great plans at the beginning of the school year for the whole year, but in the end they failed. I said to myself, “I am going to plan just for today and set a goal for this day only.”
The Satan, not being interested in a single day, left me alone. The next day, I again just made plans for that day, and so on until the end of the year.
