Today I was walking back to my hotel in NYC, thinking of new product ideas, when I realized I had been walking for longer than expected. I checked my phone and saw I had overshot my hotel by 4-5 blocks. So I turned around. At some point I checked my phone again and saw I had overshot it again by 2 blocks. Then I turned around again "paying more attention" and I checked my phone again and saw I was on the right block but couldn't find the hotel. I was on the wrong side of the street. (btw, yesterday I ended up in the wrong subway line).
