The "don't take the lift" suggestion in the screenshot is excellent. This presents a daily challenge that you can feel proud of tracking.

However, I think that this is only because it is reducible to a positive item that would be better served by a todo list: - Take the stairs.

The other ones don't seem like discrete, countable challenges. Rather they're simply part of conscientious behavior. You might as well include "don't spill milk and walk away without cleaning it up" or "don't kick your dog" in there. Unless you had serious problems avoiding those actions, I don't think it's very useful.
