Last year when it was around June, I had started selling dole whip with my family. Although I had to work the register overall, it was a great experience. The reason why this is an important part of my life is because it taught me more about how to handle my money and inflation. It also helped me learn how to work for things, such as my laptop. This is why working with me family was an important part of my life.

is this good?

Yes, this is a well-written summary that meets the requirements. Great job!
