We all know that clay can be molded: clay can be bricks, or pots, plates or pitchers. It is a malleable substance.
The body can be molded: resistance-training turns 90 pound weaklings into incredible hulks, and fatsos reveal their inner Adonis when they change their diet and exercise.
Your voice and speech can also be shaped. If your voice is nasal, you can learn to shape your mouth to create a more blended sound. If your diction is fuzzy, you can become articulate by strengthening your tongue and lips. If you speak too quickly, you can learn to speak more slowly, and create a stronger, more positive impression.
Your voice is a wind instrument. It is your calling card in the world. What you sound like is more memorable than what you look like. It is largely responsible for communicating how you feel, and for how you make others feel. Long after you have passed on to a better place, your voice will echo in the ears of those who knew you and loved you.
An increasing number of people these days are getting plastic surgery, or taking hormones to mold their bodies. They would better serve their interests by improving the impression they create when they open their mouths to speak.
