Recently I have come to the conclusion that I say "gotta" too much: We gotta go to the store. We just gotta get some Shamrock shakes. Etc. I don't like this. While I am usually pretty careful about what I say, this is a phrase that does not make me sounds smart. And since it is not a necessary part of speech, I should stop saying it.
Also "hopefully" in the sense of "it is to be hoped. "Hopefully" means "in a hopeful manner - an attitude, rather than a general sense of hoping.
So, if you hear me saying these things, please stop me. I intend to be vigilant, but it's hard. And I don't want to do something such as a quarter jar, since I find those to be more trouble than they are worth. But I am accepting ideas for something that will help me stop!
