Hikaru no Go, Kiniro no Corda: Primo Passo Recommendations
Though this anime's more on music and playing instruments, both series have main characters obtaining special abilities by virtue of a supernatural being. Both anime also deal with how these characters eventually realize their own talent.
These two show have a very similar feeling about them. Both are about rising young stars, and have some sort of spirit guiding them to their goal. Both get into difficult situations because of the mysterious abilities given to them by the spirits. And both learn to play without the help of the abilities given to them. I'd say, if you like one, you will definitely love the other. ❤

and over time develop interest for said thing.
