Looking at it logically, if we can say that it is impossible to ALWAYS do the wrong thing, it has to be, therefore, impossible to always do the right thing.
Assuming, of course, that you first have defined or identified exactly what the 'right thing' or 'wrong thing' is.

There. That ought to clear things up. </sarcasm>

LoL....clear as mud.

Truthfully, though, your point about being incapable of ALWAYS doing the WRONG thing is sorta neat in a backward kind of way. It says that on occasion we stumble into the right or work up enough fortitude to do the right or somehow get pushed into doing the right.
