When I read back over an email, I find myself editing out words and phrases that make me sound unsure. Whether it's maybe, just, perhaps, think, etc. all of these words are usually putting my communication into a less direct lane than I think is effective.
It's easier when I get to read back over something. When we're live in person we don't have the opportunity to go back and proof what we're saying.
Hopefully if I can learn to slow down my speech and my brain a little it will help with becoming more cautious about how those undermining words creep into my lexicon.
