Last Tuesday, I went to the local barber shop for a haircut. When I arrived, there was only one barber working. He was cutting a customer's hair, so I decided to leave and come back later.
After an hour, I returned to the shop. To my surprise, the barber was still working on another client. I didn't want to wait, so I walked away again. Half an hour later, I came back for the third time. Guess what? Someone was sitting in the chair again!
I realized that I had wasted the whole morning just trying to avoid waiting. Finally, I sat down in the corner and decided to stay. I have learned a simple lesson from this experience: sometimes, waiting is actually faster than coming back later.
