Curiosity is a trait of people who love to learn and grow. People who are constantly researching, asking, learning tend to be more happy. Stop learning and start stagnating. Curiosity is invigourating, it makes a person feel alive!
Ever been driven crazy by a child in the "why?" phase. They ask why about everything! Curiosity is a trait of children. May we never outgrow the "Why" stage. If we have already outgrown it...may we ungrow.
