Projects have a way of taking on a life of their own. The larger the scope, the higher the potential for disappointing results. Therefore, many projects never come into fruition.
Team members need to possess resiliency, a trait numerous inventors had long ago. They kept re-tooling until their creations worked appropriately for the masses.
Finally, there are projects an individual can agree and disagree with, simultaneously. Critical thinkers recognize nuances, after all. However, when people laugh, snicker, applaud bad results, these are miserable behaviors for young people to emulate when we consider the time will arrive when they, too, will experience disappointment of one kind or another in their development years, and adulthood.
*A strong effort is never a failure.
