The most pitiful thing there is is when people think there is nothing new to learn. There is always something new. Every day is a rare and unprecedented opportunity to learn and to have fun.
Children learn an incredible amount because they are open and unbiased.
A child can play with a stick and delight and all the while the child is learning. Learning to move and to coordinate itself. A child can watch the same movie over and over and still shudder with delight, still shiver with fear and laugh with abandon even though the child knows what is coming. Children are learning machines and have untold hours of play and joy until of course they are trained to behave like young adults and are confined to desks and told to act appropriately. Adults look for the pay off kids simply learn for the sheer pleasure it brings them.
