I know. Really hard habits to break. And sometimes we then return to using quotation marks. Try not to do that! Quotation marks are for dialogue, irony and sarcasm. Things that the reader might not get without them. They are not for emphasis, slang (we all know slang, right? Unless we're new English speakers!). I think it all boils down to that trust thing, don't you?
Glad I could be of help.
Best,
