Speakers who are good enough to get paid to do it – are not born. All of us begin with baby steps. During my basketball days, I learned quickly that you don’t get better by playing with your peers. You get better by competing with the older kids. Don’t settle for “good enough;” strive to be the best.
In the speaking world, it’s easy to get lazy and stay at your level of competence. But you can you do better. One technique is to play with the better boys. Study and learn from those who have been on the circuit a long time. They have mastered the craft way better than you and the time you spend studying them, the better off you will be. I’m not saying to copy them – no, be an original. But see how they present their topic, how they handle questions, how they involve the audience. Role models and mentors serve a very valuable purpose.
Where so you find these experts? Start with the TED talks. Google it. These are on-line short presentations done by skilled speakers who are invited to share their expertise. Listen to the stories, but focus on their style and delivery. Don’t clone them, but cull what you can.
