“The important thing is not to stop questioning. Curiosity has its own reason for existing.”
Curiosity may have killed the cat, but the cat has 9 lives. Humans unfortunately don’t have 9 lives, but then again we don’t usually die from curiosity. Curiosity is the fire of the human spirit. Consider Colombus; if he wasn’t curious about the shape of the Earth and what lay beyond ‘the end,’ America could have been a completely different country. Every great invention, every great novel, every great action was spurred by a tinge of curiosity.
Challenge what you know to be accepted, and find out if it is truth. Experiment with new ideas, and never stop asking questions. You will never know what is possible unless you push the limits and find out for yourself what is real. Be relentlessly curious.
