You cannot will yourself to be interested in something you're not interested in. But you can actively discover and deepen your interest.

Being a grandparent doesn't interest me whatsoever. Babies are all right if they're your own, but I'm not interested in other people's. It's something you tolerate because they are yours.

No, I'm not interested in politics. I have zero interest. I have interest in hope and people.

One thing that's true of gritty people is they love what they do, and they keep loving what they do. So they're not just in love for a day or a week. People who are really gritty - they're still interested.

It is important to realize that the process of 'fostering' a passion takes trial and error. It takes experience; you cannot do it all in your head. And it takes a long time.

We have found a direct correlation between grit and positive emotions, but the fact that I have no evidence that grit is bad for you doesn't mean it's not. It's always a possibility that in the future researchers will discover a downside to grit.
