Indie Thinking; do YOU have it?

My company always encourages us to have our own independent thinking (I've created the term indie thinking in short) whenever we perform our work. Professional accounting bodies embodies the importance of independent thinking by incorporating this idea of independent thinking in their professional syllabusss which their members will have to take. In fact it can be even argued that the notion of freedom lies is the ability of one to have it's own independent thoughts.

However, in reality there our thoughts and ideas will always be constrained to what we have been taught in school or through our own education. Our independent thinking therefore is never really independent because they will always be influenced by some school of thought. For instance, an accountant who belongs to accounting body ABC will always base their so called independent thinking and judgements on their education received by that accounting body and will be influenced by their concepts.

So the main question would be, 'Can someone truely have indie thinking which is free from any constraint that an education organisation puts in place on an individual?'
