Interesting perspective on life! The way I see it is, that energy is transferred, never destroyed. Leaving something behind is just a part of life, whether its something we do intentionally or not - we may trigger a mere thought in someone else's mind, plant a tree, give someone a sum of money, or just some advice, it is in some way related to us! But, we shouldn't be so attached to trying to be remembered for who we are, because as you pointed out, how we are remembered is highly subjective. Nice :)
