I've been thinking about physical activities that you can get paid for, but with flexible schedules (possible side-money to supplement investment income). Any thoughts?
Bicycle messenger -- Anyone done this? It seems like it could be too intense, and although they are often contractors, you probably still have defined hours.
Day Laborer -- Pro: You can show up at home depot any morning you feel like doing some work. Con: Too strenuous? Poor working conditions/pay likely. Is there a better version of this?
Groundskeeper -- Again, probably requires too much scheduling.
Random delivery person -- Like the people who put flyers on your door (I hate them).
