I’m happy for you that you found your purpose in life in caring for someone. Imagine the world where everyone is cared for so that there is no need for your care. What would you do?
Pretty much the same as if I were immortal, try being good, try being bad, try hedonism, try suffering, try imparting suffering, etc.. until something gives and starts making sense again.
So you are saying the Matrix script should have had Keanu just heading to the beach, and not being thrown into one adventure after another, to discover himself?
hmm...that would have made an interesting movie.
The brightest minds of this world did have time to concentrate on and to develop their creativity :) Though it’s your life and therefore you have to decide what to do with it. Caring for someone might be a better choice then not doing anything at all.
