24. Public Speaking

If you’re an expert on a particular subject and are also a dab hand at presenting, public speaking could be an extremely lucrative side business for you.

You may have to start by speaking for free (or at least for only a small amount of money) but, if you can build up a reputation, it can be a very good thing to do on the side. Create a course, give seminars, market yourself and away you go! You’ll have to go about it differently depending on what you intend to speak about, but do the correct research and you’ll stand a good chance of success.
