I hear this in daily status meetings: “I hope to finish X today.”
(I’ve said it, too. I’m not immune.)
Best I can tell, “I hope to finish X today” really means “I want to tell you that I will finish X today, but don’t actually have confidence that I will finish X today.”
Commit. If you have to commit to less, so be it. And don’t be afraid of being wrong. With practice, you’ll get better at knowing what you can commit to.
