though i have pretty much stopped commuting via 2 wheels, since i moved down here and (for now) only live 4 miles from work. but when i used to do my daily trans-bay commute, i loved it. it was fun. as crazy as it sounds, i find it more fun than going out on weekends "conquering" the twisties. i love splitting lanes, i love feeling of moving when others are stuck sitting. i love how it keeps my alert level up. i love cager watching, seeing all the crazy things they do and predicting/anticipating what stupid move they will make. i love how im getting fresh morning air and be all pumped up by the time i get to work/school.
my point is, u got to find things that keep the commute fun. if at any time u find urself feeling like ur commute is becoming a duty, or some type of obligation, then it might be time for u to either take a break from it, or stop completely.
