Single water temp control knob in the shower

Do you do this in the shower?

When it's to cold, you think, "Wow, I needs less cold, turn it to the right to get less cold water"  (wrong decision).
Or, when it's to hot, do you think "Too hot, need more cold, turn it to the left". (again wrong).

I've done this forever.  Can't ever get it right in the heat of the moment.  Pun intended.
