Committing is a personal matter. It is about dedicating one’s resources to an idea, a plan, a project. It involves going through the different possibilities and scenarios, the different allocations of time, energy, money, and picking one we feel we can give ourselves to. This is also the reason why committing publicly is so important. The moment we share our commitment with others, the commitment is still our (personal), and yet our very own personality is in jeopardy until we deliver. This is a powerful force to get things done.
Promising is different. A promise is always influenced by someone else, and that is the opposite of personal. You promise to change a status of the world because others are affected (negatively or positively) by that status, and yet not necessarily there are resources invested in the moment you are promising. Promising publicly is a pleonasm, as a promise is always done to someone else. Promising is easy, and that makes it also a powerful force to not get things done.
Commitment is about understanding what’s important and devote to it.
Promise is about grasping what’s urgent and put a temporary patch to it.
