Want to be famous in your field? Speaking engagements can grow your audience, your profile and your credibility. To gain experience, start small and build from there. Some opportunities include local schools and colleges, as well as local business events. Join a networking group and offer to give a presentation, making sure to mention that you are looking for more opportunities to help people. Attend events that you would like to speak at and approach the organisers to share what you can offer. You can also speak to industry based conference companies and offer to share your skills at their next event.
