Bob and I released Startup Success Podcast #129 yesterday, featuring an interview with Michael Sliwinski from Nozbe. Nozbe is a web app to help you implement the Getting Things Done (GTD) methodology introduced by David Allen.

I met Michael at the 2011 Business of Software conference. In addition to being a successful entrepreneur, he’s just a great guy. His passion for GTD and his product is infectious, and he is very generous toward other startup founders as well (he’s making a point to cheer me on, in fact).

The key point that I take away from Michael is not to get too carried away with Customer Development, marketing, and Lean Startup – it’s a reasonable strategy to to build a product you’re passionate about and keep at it until other people fall in love with it, too.
