One thing I’ve learned is not to put off a good deed or backing up a device or process that has no fallback.
Now, some things are too big and expensive to back up. Think home HVAC etc. So have a fallback.
Good deed? You might not have the opportunity again!
As a combination of the two above, I once (long ago) scheduled to start a weekly tape backup of a university research group’s data drive for Friday when I could have done it on Wednesday. It melted down. Things are immensely cheaper now, and you just buy a backup drive.
Doing that good deed (or smart deed) might cause some inconvenience or near-term cost. Put off things that are less magnanimous or without a crutch.
I read a book called “Woulda, Coulda, Shoulda” These things block progress. While the two items mentioned above aren’t all you need to do, they are steps in he right direction.
I posted the blurb from this book in the thread:
