When starting to work on something, I generally do a sanity check to see that the fundamentals are there and correct versions, then throw that part of the context out of mind, knowing that I stand on firm ground.

I found out that with this verify-and-forget step, I work much more efficiently.

As a result, my workflow becomes independent of the machine I work on, because I become the tool, not my setup. After that point, only having a "$" at the beginning of the line is enough.

Of course everyone have their own choices, and YMMV.
