Caleb is only one. He's just learning to walk, so he falls down a lot. Nobody minds. We expect it, and unless, he hurts himself, it's kind of funny. When he takes a few good baby-steps before he falls, we cheer and clap. Maybe that's why he always pops back up and tries again.
If you've fallen down a bit in your steps toward intentional gratitude, remember Caleb. There's only one difference between the person who succeeds in cultivating new, healthy habits and the person who fails: the person who succeeds gets back up every time he falls. And, if you have a buddy learning with you, the accountability makes getting back up a whole lot easier.
