There's a concept in the sales world called KISS vs. KILL. Keeping it short and simple versus keeping it long and lengthy.
Amateur salesman would "KILL" the sale by going on and on about unimportant details. A good salesman on the other hand would hit all of the important points in the shortest time possible and close the deal.
Tip#1 is to be efficient with your speaking. Conversation is all about quality.
Try to remove all types of filler words like, "Uhm, Like, I Guess, Well, Uhhhhh, You Know." These words bring no value to the conversation and they literally mean nothing.
Listen to the following paragraph. What did you do this winter?
Well, I had an ok time this break. I went snowboarding for the first time with some of my friends and uhm. . . . well it's actually a lot harder than it looked.
Uh. . . that's about it. I guess I had fun haha.
Now compare it to this, "What did you do this winter?" Me and my friends went snowboarding. It was actually my first time and it was a lot harder than it looked.
Notice how the second version is much shorter, but the information being conveyed is the exact same. However it sounds more confident and even more sophisticated.
Don't be afraid to take pauses instead of relying on filler words as a crutch. Pauses can be powerful and can emphasize different parts of the message.
