Chances are, you won't be remembered in 1000 years. And you'll be too dead to enjoy it if you are. Are you sure you have come to terms with that? Lots of people I meet here are obsessed with "making their dent in the universe" and I think some of it is driven by the fear of death.
That said, if you just want to better the lives of future generations, there are plenty of things you can do now. Give money to good causes. Get involved in politics. Plant a tree.
