Here's some inspiration for you...
Being good at something means nothing. If anything, it means you haven't dedicated your time and interest to enough endeavors. While the hard work that accumulates into "talent" might be admirable, that admiration is always measured by how obvious and appealing the resulting "talent" is. The best hole digger in the whole world will likely be applauded as a dedicated and industrious person until it's discovered he's only digging a hole and for no particular purpose...then he's a moron.
It could be that we're only throwing dirt over our shoulders, breaking our backs while hoping to hit a vein of validation that's forever one foot further down, our hard work only confirmation of how deep the hole is we've dug ourselves into. Will our children cheer from the rim of our quarries, celebrating the dedication to our labor, or will they find a spring at the bottom of our wells? I'm frightened that all of this is for nothing, but if the fruits of our labor aren't for us to enjoy, I certainly hope our efforts pull back the sod for future hole diggers.
The purpose of life might be to preoccupy ourselves with hard work and other distractions until we die unexpectedly and in disappointment. If a legacy is something we all leave, I really hope mine has something to do with keeping busy instead of the trivial byproducts of my labor.
I cringe at the idea of an epitaph, but if I were to have one, I'd prefer it said something like this:
Wyatt worked relatively hard on several occasions.
