You'd be remembered by your immediate family for the duration of their lifetimes. The memory dies with that generation. It's the same for everyone. Personally, I don't think the purpose of life is to be remembered.
Life by it's very definition is pain and suffering. Doesn't matter who you are. Same rules apply. Pain isn't a nice experience, but it does make you stronger. Lifting weights at the gym isn't exactly pleasant, but it keeps a person fit.
