From A Weak to Confident Communicator - 30 Day Challenge
People have a tendency to speak in the same manner to the person of every age. But every person thinks as per their age and experience.
Recall how your thought process was 10 years ago. You thought, behaved and spoke differently. If someone had to convince you 10 years ago, he had to use different words compared to what are necessary now.
When you are talking to a person 10 years younger or older to you, realize that they have a generation gap. Tweak your words to match the thought process of the listener to make a better impact.
Today, you must change your words when you speak to a younger or older person.
