No more structural induction for you!

I've just got home from a three day trip together with people from my work. We stayed in a hotel which had a nice lounge with a grand piano. There where a few of us who spent some time there playing and singing and having a very nice time in general. After having heard me playing a particular piece one of my colleagues from the algorithms group told me he thought I was really good at playing. I responded that I don't play that much anymore, maybe just once a month. He thought that was a real pity and gave me the following comical yet very nice exhortation:

You should stop doing structural induction and play some more piano!

It's a very nice quote.
