The best way to expand habits is to build on an existing habit and make it part of the habit.

Here’s my recent use of this technique: I always forget to water the lawn (and when I remember I sometimes forget to turn it off) as a result the grass in the little patch in front of my house turned brown. On the other hand each morning I go running- it’s a habit that I instilled by having my alarm going on early. So now I just turn on the sprinkler (a hose with a plastic oscillating extension) when I start my run. When I take my son out to wait for the bus an hour later he or I turn it off (it’s either that or walking through a shower- so we’re forced to do it).

What habit are you building?
