During my studies this past summer reading various pickup books I’ve learned to eliminate the words like, uh, um, and you know from my vocabulary. I read and have learned to not say these things because it makes you sound more clear about what your saying. You sound more certain and confident during your conversations with people. I still do catch myself saying these words sometimes but I’ve noticed the powerful effects this has on people when your speaking.
I’ve noticed most people out there use these words quite often when I speak to them. Try to remember this and give it a shot. It will help you trust me. You will also start to pickup on how much other people use these words and you realize how uncertain of themselves they sound.
I’m throwing this out there and hope this helps.
