Just went on an extended ride through the east side of Portland in the rain, on the bike I received yesterday. The combination of weather, and my old bike being slightly out of commission for a few weeks means I haven't ridden as many places I was before. Winter can sort of make you forget how great going outside and doing something — even a little — physical makes you feel. Your body feels better, and your brain works better.
Anyone serious about development should be serious about how they treat their body. Both with what they eat, and what they do.
