I hear you. The prospect of living forever on earth gave no urgency to living life in the now. Leave it till the new system! You'll have plenty of time to study, learn music and do your own thing then! So you never needed to think about life goals and if you did, it was more of a fantasy.
For the now, my interests come last and my family's interests first. My down time now is reading and researching all of 'this' and I am becoming consumed by it.
I still don't think that I am living an honest and authentic life but will integrate more things in every now and then. Hence my garden goal this year :)
Guess what. I want grandkids to pick fruit from nanas garden. Didn't ever think about having grandkids coz surely that would be after a thousand years. Good god yes it is layers and layers of cultedness.
