I've recently watched a TV series called "Moon Machines," which looks at the engineering side of the Apollo program. These are people who used their brains to solve novel engineering problems, under intense pressure, and accomplish something great.
Side note: many of them reported working crazy hours, for months/years at a time, and the pressure on their families led to a huge divorce rate.
So... maybe achieving something "great" isn't all its cracked up to be.
The great thing about having high ability is that increases the number of options. But it still comes down to this: What do you want to do? If you want to do something great, go for it. And feel free to define "great" as whatever it is you want it to mean.
Personally, I've been all around the world (literally) and done some really interesting things, but being a dad is the greatest adventure I've ever had.
