An engineering suggestion from PeakSufficient2839:
"Setup your favorite terminal program to log EVERY session. Make a folder, put it somewhere you'll remember, and log all your sessions into it. I called mine ‘Sessions’ and put it on my desktop. This works wonderfully for tracking config changes, remembering CLI commands, ‘show’ commands from weeks ago etc. I've come back to files over and over again, finding relevant info from previous events. Totally worth it."
