This comment by Chris was on "People tend to like their own opinion more than your opinion" - a bit of an older post, and a nice comment, I thought it was worth making sure everyone saw it -

Hey Sebastian, nice post and nice blog! I'm a new reader this week... As it happens, I am a single founder as well but already have some investors / experienced startup guys on board. And every time we have a difference of opinion, the scenario you describe plays out anew! I have learned that my opinion has a multiplier attached (like -.5 perhaps), and the multiplier is significantly smaller then theirs. :) Over the last couple of years I've really struggled with the line between listening to their advice and taking it even when I think there's a better way. One big example stands out where they thought I should do A, I thought we should do B, and I had tons of research to support my ideas. We did B, and when the dust settled I was completely wrong. In the end we learned from it and failing is where you practice succeeding, so I don't hold it against myself. You have to take risks and put yourself on the line. But the lesson reduced my stubbornness by a lot and these days I try harder to understand the voice of experience, and really question my ideas before I get attached to them.

Good stuff here.
