Launching new habits

"Habit is the enormous fly-wheel of society," William James wrote in Principles of Psychology.

In Talks to Teachers, he elaborated:

in the acquisition of a new habit, or the leaving off of an old one, we must take care to launch ourselves with as strong and decided an initiative as possible. Accumulate all the possible circumstances which shall reinforce the right motives; put yourself assiduously in conditions that encourage the new way; make engagements incompatible with the old; take a public pledge...

The old "new habit" I'm doing my best to launch these days: writing habitually, daily, as my highest (or at least my first) priority.

There, I've taken the pledge.
