PERSONAL ESSAY -- Science Fair: topic to avoid?

Would it be unwise to write my Common App personal essay on an experience at a science fair? I’ve been cautioned against doing so because it is a go-to topic. I believe that I have taken somewhat of a creative approach to the topic, and I have confidence in my narrative abilities, but I’m worried that it may still be too typical.

The topic you choose is far less important than what you do with it.

If you feel you have a creative approach and good writing skills, go for it! If you have an interesting spin or feel strongly about it, go for it!
