What's the point of living if...?

I don't, I know there is no God, and no plan. I effect this world in the way that I choose. I know that when I die everything I think of as myself will be gone. I also know that of the stars in the sky some have died millions or billions of years ago and yet their light is still traveling to us. The light that I choose to shine may be felt, shared and experienced for generations after i die.
