Notivation

When someone tells you you can't or shouldn't do something, you are somehow more motivated than ever to prove them wrong. Notivation is a specific category of motivation that comes from being underestimated, misunderstood or written off. Can also be used as a verb: to notivate or to be notivated.

My boyfriend told me that he thought I was too lazy to ever move out of home. That was exactly the notivation I needed to start saving money.
