I think it's great that you have sooo many interests! I don't think you should see it as 'spreading yourself thin' when you love many different things. There is a concept called synergy which is when different aspects that have seemingly no to little relationship feed into each other to produce a result that is far greater than just adding the bits together.
If you really love all these things, then keep on doing them - at some point it will all come together and it almost certainly adds and contributes to your personal fulfillment. We love the things we love because we love them - denying yourself any of it will not contribute to your happiness and success.
