Auction Power Guide

I have to have my topic picked by tomorrow, and I am not sure which one of these to pursue. I am very interested in both of them, but I can only pick one. I already play the piano, but I think learning to play the guitar would be cool too. On the other hand, selling on Ebay has been interesting, and I would like to incorporate that for my project, as it relates to business. Thanks for any and all answers!

I would go for the guitar. It’s a skill you can retain your entire life. And you can have fun with it. My niece learned to play and was invited to parties all of the time.
