So, as a business person and entrepreneur, what is your biggest blunder ever? For me, I have to say it was not keeping one of my companies in the 80's on a path of constant change. I allowed the company to locked in on a narrow product line that was aging along with legacy clients in the computer industry. I didn't react fast enough to changes in the industry and had to turn it over to my junior partner. I spent a year reflecting on how this happened and it was a hard set of lessons learned for me. I am a bit obsessive now as a result. I am constantly staying ahead of the curve these days and sometimes I have to stop and take a breath when I get hypervigilant. What's your biggest business blunder?
