“If we had always thought from a so-called practical angle – we would’ve never had anything new in this world. We would’ve hidden under the security of practicality and taken no risk, we would have never discovered heart transplantation as a new possibility, we would’ve never thought curing cancer patients a possibility, and we would’ve never discovered a new galaxy in the universe. Taking the cover of practicality is more or less like hiding under the cover of security for fear of failure.”
