A physical post-it note on your monitor that you don't take off until you've used it three times.

Or some other similar reminder -- perhaps just a list of things you're going to install when you need them, so you don't install them until you have a use.

(I have this problem too)

When I have a similar conundrum I typically add it to my calendar at a random time as a helpful popup/reminder.

Usually I don’t even need the reminder, just writing it down is reminder enough.

Make this alias for whatever log viewer you use now.

  alias tail='echo "use toolong instead"

Now using tail to view logs will print that reminder instead.
