Expect flitting from interest to interest. Love of Learning Phase, at whatever age you come to it (many adults need it, too), is about learning what interests you, a little of many subjects. Don't invest lots of money in long-term lessons; try it out first, and don't be disappointed if your children decides this isn't the thing to learn after a short time. We can keep learning and even switching careers in our 50s; there's no need to feel bound to a particular endeavor if it's not helping.

I hear some, "but he must learn to stick to it, to keep on until he masters it; he must learn that life is not all fun and games." These are true and valid concerns, but they can be better taught by things that have obvious consequences: Dishes. Laundry. Clearing and vacuuming the floor. Gardening. Preparing meals and cleaning up. Service to other people. Sure he will eventually need more math, but it has no real application at age 10; it can wait. You probably wish you'd played an instrument more or learned gymnastics, but if it's not on his fun list, if it becomes a chore, consider dropping it. You can always pick it up later if he misses it.

My finances have not allowed my children to be in sports and dance and martial arts; but even if we could have afforded every class, it's not worth making life a drag to be in everything. Choose what's bringing the most value to your child's life. And (I'm smiling) beware of trying to push your child so you can get bragging rights. No! This is not about you. This is about your child finding his or her mission in life. Which is Not the same as your mission in life.
