Our deeds determine us, as much as we determine our deeds.

What you do keeps voting on who you become. You choose an action, and the action turns around and settles a little more of your character into place, so the next choice comes from a slightly different person. Small repeated deeds are not only expressions of you; they are the material you are made from.

Pick one action you have been treating as minor and ask what it is quietly building. If you would not want to be the person that habit makes, change the habit rather than your opinion of yourself. If there is something you want to become, act it once this week before you feel ready.
