Richard Feynman's approach to the collection of knowledge is one of the inspiring things I've ever encountered (thanks Nick Howes). If you haven't read "The Pleasure of Finding Things Out" then do it now. Take nothing as gospel. Be curious. Don't respect authority. Don't fear uncertainty. Embrace it. The people who are sure of their answers are the ones who scare me the most. Doubt is often seen as a weakness in business but it's in no way a bad thing. Doubt combined with optimism brings out the explorer in all of us.
