I've never wore my company logo. Perhaps that means I'm not passionate at what I do, and a bad fit for startups.
Or it could mean that I separate my job from my life, and consider them two different things. Perhaps it has no impact on the quality of my work, or my willingness to work with others.
When dealing with people, making grand statements about how to make the right decision feels wrong. We're all our own world, filled with our own opinions, thoughts, and desires.
I think the sooner you recognize the inherent differences in people, the better you can make quality decisions based around how they will fit in.
