Don’t judge each day by the harvest you reap but by the seeds you plant. ~Robert Louis Stevenson
The number of seeds planted is a lead measure, one over which we have direct control. Harvesting, on the other hand, is a lag measure, proportionate to the planting, but governed by many conditions (sunlight, temperatures, precipitation) outside our direct control. Planting seeds is a controllable. Choosing where to plant seeds is a controllable.
