in alt.windows7.general the following:

I say trying _beyond a point_ is unproductive: of course, it is
intensely rewarding when someone "sees the light", as in "now I see what
you're getting at" - which is why we all try (-:. But it's best to be
able to see when to give up! (And I'm probably as bad as any, at not
seeing.)

Lack of repeated use can also change things. I used to know fluidly a
4GL programming language. Spent 10-15 years doing it and was dang good.
After years retired, I have little hope I could redo it. I could
possibly read it, but engineer it or improve on it, NO.

I can read GD&T, but not sure I can "write" it. {"Geometric
Dimension and Tolerance" : machinist / design speak for "how to set
the values of "good" to make sure the parts are "good"}
