It is always safe to assume, not that the old way is wrong, but that there may be a better way.

The practical man is the adventurer, the investigator, the believer in research, the asker of questions, the man who refuses to believe that perfection has been attained.... There is no thrill or joy in merely doing that which any one can do.... It is always safe to assume, not that the old way is wrong, but that there may be a better way.
