An audience will often give proper observation to a public speaker that keeps his message simple, clear, and easy to grasp.
Also, nobody likes a bad public speaker and gives their precious time under the trademark of a boring speaker.
Here’s the good news folks: you do not have to be a natural born public speaker!
If you doubt me, here is what I want you to do: think of a famous leader, titans of the industry, politicians, or anyone that you admire, go to YouTube, and find the oldest video you can possibly find of that person. It can be Bill Gates, Steve Jobs, Mark Zuckerberg, or anyone else. You will find them giving speeches that are truly horrible.
That does not mean that public speaking does not matter. What it does mean, is that you can overcome the problems that you face doing it. All those people that I just mentioned went on to become great public speakers which means that it is not a natural-born skill. You can certainly learn it.
Even the people that you think are highly successful have had horrible speeches. So do not beat yourself up or just give up if you are not currently a great public speaker. But you must be willing to improve proactively.
A bad speaker can also become one of the most impressive speakers who motivate and convey precise, clear, and easy-to-understand presentations.
Although, this requires knowing the bad habits and avoiding them, round-the-clock practice, and time for proficiency.
Understanding the above qualities that make a horrible bad public speaker and keep them away will make you one of the finest public speakers.
I generally encourage you to look at great public speakers so you find a role model and inspiration, but sometimes, nothing is more motivating than watching how awful some people used to be who have now achieved a tremendous amount of success.
