Most people spend most minutes of most days doing one thing after another. I sure do. Typing these words is a kind of doing, as is driving to work, making dinner, brushing one's teeth, or putting the kids to bed. For all the "labor-saving" devices of the past 50 years -- dishwashers, phone machines, word processors, etc. -- most of us are laboring more, not less. For example, in terms of employment, the average work week in America has gotten longer over the past 50 years. Meet someone and ask how he or she is, the answer is likely: "busy." Doing is a huge part of life, yet we don't usually bring much awareness or wisdom to it.
Sometimes doing feels good. There could be a sense of flow in everyday activities, pleasure in your own skillfulness or competence, or fulfillment in helping others.
