Speaking of Douglas Wilson, this old post he wrote on the fruitfulness of plodding is insightful. Excerpts:
I believe in plodding. Productivity is more a matter of diligent, long-distance hiking than it is one-hundred-yard dashing. Doing a little bit now is far better than hoping to do a lot on the morrow. So redeem the fifteen minute spaces. Chip away at it. For example, I have a stack of six books that I am working through most weekday mornings — a page or two of each every time I sit down to read. I do the same thing with writing — if you have time for a little bit, then do a little bit.
A sixty hour work week is an honest job and a significant load, but a lot of the problems that come to people who work this much happen because of where those sixty hours are placed. It is possible to work sixty hours and still have lots of time left over for family. A week has a total of 168 hours in it. Sixty hours of work leaves 108, and eight hours of sleep a night take away another 56 hours, leaving you with 52 hours a week to play tag with the kids.
Read the whole thing.
Also, from the parts I’ve read, this 36-page booklet by C.J. Mahaney on biblical productivity seems quite helpful–particularly at making a distinction between busyness and fruitfulness. Plenty of “busy” people are relatively unfruitful and unfaithful to their deepest priorities, and its a temptation we all face.
