I can remember the Tools and Techniques & Outputs but have difficulty remembering the inputs.

Any suggestions on how to remember the inputs?

I know I shouldn't try to memorize them. I am not trying to memorize.
I remember the outputs and TT fairly naturally but not so lucky with the inputs.

Is there a good way to think about inputs that will help me remember them somewhat naturally?

Would appreciate any comments on why its harder to remember inputs when compared to outputs or TT? Anybody else in the same boat?
