Curiosity is a powerful tool. It makes us question our surroundings and compels us to ask why things work the way they do. It kicks the mind into exploration.
But the addition of courage takes curiosity a step further; it tries to fill the void through hands-on experimentation. These small tests are fuel for failure in disguise as they convert ignorance into knowledge.
The greater challenge, therefore, is the audacity to continue guessing. Even when something gets discovered, it opens up a whole new can of ignorance.
The learning never stops if the asking never stops. The more we know, the more we desire to know.
