Are facts really true?

I found an interesting line in David Neagle's writing as today's guest on Inspire Me Today. He says, "...facts are only facts until we become aware of another fact that supersedes the previous".

This is so true. Science makes new discoveries and we throw out decades or centuries of common belief. The same is true in our lives on a daily basis. We develop beliefs from experiences we have. Every new experience has the opportunity to alter that belief.

I have found that questioning my own beliefs has been a huge help when it comes to creating or doing something new. What beliefs might be holding you back?
