i was raised by parents who valued life, and had suffered sad losses of loved ones in (what we like to believe) premature death. they lived before many vaccines we take for granted were available. polio, and others. they lived in gratitude and did not take life for granted. (i believe) this was common, not exceptional.
“living each day as though it were your last,” was a common thought, as were thoughts of living in ways that loved ones knew they were loved, not in words, but in actions. the word, “love” was so highly regarded, it was not frequently used in my home growing up. my parents did not want its sacred value to be diminished by overuse, they tended to be mistrusting of those who used the word freely. (i respect their stoic ways, but, as parents, we were not so strict that way with our children.)
Wayne, i don’t think there’s much to add to your words in another thread:

The cancer has spread to multiple organs in my body. It is inoperable and the plan is palliative care - there is no cure. I start chemotherapy next week to slow the spread. I have a year to live, possibly two. The good news is that none of my major organs are damaged at this point and we might be able to stay ahead of that. The doctor says that the cancer will eventually take up all my energy and I will just waste away.

We know that God can be honored by this, either through a miraculous healing (which would be fine by me!)
or by the testimony of our faith and endurance through the strength that He gives.

I do not plan to spend 12 months dying, rather I plan to spend
12 months living.

We are thankful to be given this time as we have friends who were suddenly widowed with no warning and who faced their future completely unprepared.

I am blessed with a devoted, loving wife (we will celebrate our 44th anniversary in June) and family;
we will make a few more memories and get prepared for my leaving them behind.
Continue to remember me occasionally when you pray.
i believe in prayers and miracles. they happen. i’ve witnessed some in my real life, i’ve read about some here.
let your family love you and care for you. there may be some unexpected role reversal, let it be. God allows it, and blesses it.
i had a “brush” with a dire, possibly terminal illness about 10 years ago.
my thought processes were much like others are describing here. i had major surgery, and was cleared of the scare.
there are no rules.
if that bridge comes again, i’ll cross it. it may be another bridge.
as you say, not everyone is given time to prepare and say good bye. time is a gift.
we all have to deal with God’s will, with His timing.
i believe in prayer. i believe in miracles. i believe many fervent heartfelt prayers are being said for you.
take each day as it comes. be grateful for it. as you say, LIVE IT. LIVE THAT ONE DAY. and keep going as God wills.
follow doctors’ orders, but forget about what they say. as you say, LIVE. LIVE, anyway.
for your family as much as for you, i pray you have years of “one day at a time” with them yet to come.
