This Drabble strip speaks to me. (Edited to fix link.)

Yeah. Flubbed the URL in the email post and then couldn't fix it until I got home. Thanks.
what i find far more attractive are ideas about changing the way i spend my time
Yes. I'm willing to parallel-process; I'm not willing to give up anything I'm currently spending time on. Now, to figure out how to do that...
(I should get myself a bicycle. Riding it to work probably won't happen, but I could use it for some errands without much loss of time.)
