I still wrestle with memories of pre-motherhood me who could have a full time job, commute, and still get in many hours in the evenings/weekends of whatever hobby had my attention at the time. 20 minutes adds up and is good for me, but it feels so little when a few years ago I could have spun this same yarn in less than a week. (And in a day or two when fiber arts was my job! XD)
