It's a frustrating life lesson I was reminded of quite recently. I had a potential keynote speaker for Demo Day this year I thought was perfect. (Shameless plug: StartFast Demo Day is on Thursday August 9th. Sign up for our newsletter to find out more!) The prospect could easily draw a big crowd, I had a direct connection to get to him, and I even found our first sponsor. Things were shaping up well all things considered. It was at that point however that reality hit and things got aggravating. I had a conversation with one of my mentors who reminded me about opportunity cost.
