Habitologists33 call connecting a new habit to a current habit “habit stacking.” It’s especially helpful because of the way your brain works. Your brain builds up connections between neurons that are used frequently. Your brain removes connections between neurons that are not used. (That process is sometimes called “synaptic pruning.”) Those removed or “pruned” connections are why it’s so difficult to remember something you rarely do and so challenging to start doing it. Your built-up connections are why it’s so easy for you to remember to do things you frequently do and to do those things.
