Like @canidmajor , I hope my legacy is to be remembered for being a good father and raising two great kids.
One of the harsh realities one learns as they pass through their forties and older is that it is very rare for anyone to have a legacy that lives more than 50 to 100 years after they are gone.
Rock Hudson was one of the most famous people in the world, recognizable everywhere, and he has movies and TV shows available for posterity. But he died in 1985, and I wager few people under the age of 40 know who he was.
And as memories of my own father fade from collective memory, I realize the best I can hope for is that 50 years from now my children have a fond memory of me.
