"Are you really sure that a floor can't also be a ceiling?"

This quote by M. C. Escher is a pointer to think outside the box and to think about the possibilities of what might be. It encourages us to look at things from a different point of view and to think about the potential of what could be. It recommends that we ought to not be limited by our preconceived notions of what something is or should be, however instead to check out the possibilities of what might be. It is a pointer to be unbiased and to believe creatively. It is a tip that in some cases the most unlikely of things can be possible. It is a reminder that we must not be afraid to challenge the status quo and to think in a different way. It is a suggestion that in some cases the most unlikely of things can be possible and that we should not hesitate to explore the possibilities.
