Most people can learn a lot more than they think they can. They sell themselves short without trying.
There is no man living that can not do more than he thinks he can.
We don't always have an accurate view of our own potential. I think most people who are frightened of public speaking and can't imagine they might feel different as a result of training. Don't assume you know how much potential you have. Sometimes the only way to know what you can do is to test yourself.
Perhaps I have a wider range than I'd given myself credit for.
Often we don't have a good notion of what our talents are, because we have never had a chance to try them out.
I don't set goals. Competing with a number in your head can be limiting, and I don't know what my capabilities are yet.
In order to press further with who you want to become, you have to take risks, put yourself out there... That's the only way to discover you're actually capable.
Maybe the fear is that we are less than we think we are, when the actuality of it is that we are much much more.
