I also read moonwalking with Einstein and it's such a great read that I committed to memorizing the first digits of Pi. Which I did using my own custom PAO system.

And then the payoff... When I would tell people I could recite the first 100 digits of Pi they would be interested and say I want to hear it. So I would start and after about 20 numbers they would just say I believe you and that would be it. So I let that skill lapse.

I think my new talent would be better spent memorizing my credit card numbers and driver's license ID.
