I have no duty towards life. I didn't choose to be born, did I? In fact, I vegetate waiting to have enough strength to suppress my fear of death and kill myself.
Yes, I've tried therapy in the last 15 years. Yes, I've tried exercise, meditation, journaling, workaholism, idleness, religion, philosophy, science and so on and on. I just want to be done. Every evening I pray to deities I don't believe in: "Have mercy on my suffering, do not make me wake up".
So, no: there is no duty towards anything, just the futility of existence in itself.
According to the Bardo, Veda, Platonic Phaedo and Tibetan Book of the Dead, yes you did. You just don't remember why your immortal soul chose this adventure.
> Every evening I pray to deities I don't believe in: "Have mercy on my suffering, do not make me wake up".
And every night s/he answers your prayer.
Try it with a different twist. "Have mercy on my suffering, help make me wake up and remember"
There's a funny line in "Analyse This" where Bully Crystal's character says innocently to Robert De Niro...
"What are you going to do this summer?"
"About What?!"
