Free time is the problem.
Headspace is a wonderfully humane app designed to improve our well-being through daily meditation. For a little social validation, the app provides the number of people meditating along with you at that moment.
One might expect that the number of meditators rises on evenings and weekends, when people are out of work. Instead, the opposite trend unfolds: fewer people meditate on nights and weekends than they do on weekdays.
The people who insist they “just don't have the time” also tend to be absent when they do.
If you are citing your constraints as an excuse to not take action, then you don't have enough constraints.
A little less time, a little less funding, a little less freedom to avoid (or accept) the consequences; each constraint nudges us to the edge of the diving board. And then we leap.
