"Minimize extra, unnecessary words that take up space but communicate nothing.
This is similar to the productivity tip of removing unnecessary action from your life."
"Get rid of filler words such as 'umm...' and 'uhh'.
These words don’t actually contribute any value.
If anything, they remove the impact of what you are saying because they reveal the insecurity that the person you are dealing with will leave you if you pause for too long."
