You can always wait until you're better.
Until you're a better writer.
A better public speaker.
A better artist.
Or a better person.
But the truth is that you'll never become better at anything just by waiting for it to happen.
The only way to become better at anything is to do it. Over and over and over again.
Reading about it won't make you better at it.
Waiting for it to magically happen won't make you better at it.
Only doing will make you better at it.
So let's do this!
