There's much to say about "wasting" your off time by learning your editor.
I still remember this one time, 15 years ago, where I spend literally the whole night configuring my .vimrc, reading the :help pages for all of the configuring options, doing the tutorials, and just moving around and getting comfortable with it.
At 8PM that night I didn't know Vim, but by 6AM the next morning I was very productive in it. I'd say about 80% of my productiveness with Vim was achieved that night, and I could never change to a non-Vi editor since.
