Purpose rarely arrives as a wave of feeling. When it does, it usually drains by Thursday, and people conclude they have lost it.
The durable kind accretes instead. You do one thing that fits, then another, and after a year a shape appears that you didn't plan — the way a footpath wears across a lawn from people walking the shortest line.
Feeling upbeat is pleasant and not required. Plenty of purposeful days are entirely ordinary from the inside.
Rather than waiting for it to permeate anything, put down one more step on the path today.
