I was invited to speak at Small is Beautiful in Glasgow, so I travelled domestically to speak. The event gave me a free ticket, and I was paid 500 GBP to speak. My travel and accommodation was fully covered by the event. My employer did not pay my travel expenses, and I took unpaid time off to speak. It took me 3 days to prepare for my 20 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 1 year. Also, Everyone is scared of public speaking. That doesn't go away. But you can learn to harness the energy from your fear, and convert it into a good thing.
