I proposed an idea to speak at Midwest.io in Kansas City, so I travelled domestically to speak. The event gave me a free ticket, and I was not paid to speak. My travel and accommodation was fully covered by the event. My employer did not pay my travel expenses, and I was working while speaking at the event. It took me 20 days to prepare for my 40 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 10 years.
