Most books or articles I’ve read on habits converge on the same point: remove decision making and the need for will power.
If you expend zero energy making a decision about whether to do something or not, you’ve got a little more energy to just do the thing in the first place.
However, when self-negotiation is involved, there’s always going to be a good reason to back out.
Being selective about our habits is important too. When we have too many, life can feel like an endless routine of chores and must-dos.
Pick a few that matter. And don’t negotiate.
