I've found this quote to be quite true. I use small moments to accomplish many small things and it is amazing how much actually can be done in those small moments. A lesson I was forced to learn between my own limitations and the demands of babies and small children. Now I use it between my reading and writing demands.
"Much may be done in those little shreds and patches of time which every day produces, and which most men throw away. " ~Charles Caleb Colton
