Even so, I can hear you say "It's all good, I feel its worth it" and "You are depressed man". We like to give excuses for the inevitable so we can continue going on ourselves.

Did you meant that the phrases there are excuses? I didn't understand what you meant here I think.

I don't see why we would need excuses to accept the fact of life that you are pointing out. What's the problem with realizing that you will not be remembered and nothing much will be left from you after you die and living a happy life?
