If your words don’t portray who you are, what does?

People make mistakes in the words they use, I often think “oops, I shouldn’t have said it like that”.

If said once, yes.

Actions? I generally judge people by what they do, not what they say - though of course I have to admit that saying things does fall under "doing something", if it's impactful.

The truth is that both words and actions communicate something, especially in combination. And sometimes words are the action.
