Environment often matters more

Small changes in context can lead to large changes in behavior over
time.

Every habit is initiated by a cue. We are more likely to notice cues that
stand out.

Make the cues of good habits obvious in your environment.

Gradually, your habits become associated not with a single trigger but
with the entire context surrounding the behavior. The context becomes
the cue.

It is easier to build new habits in a new environment because you are
not fighting against old cues.
