'There's nothing so practical as a theory' to paraphrase Kurt Lewin. This means that your 'philosophy' determines how you act. In particular it means that how you 'see' a problem determines how you 'see' the solution (sic)

Just imagine...this is Simple Nick in 'restrained' mode. What would he be like if there were no restraints?
