Support your kids and the people you care about. They aren't going to get it right the first time. They may not even get it right the 10th time. But maybe the 100th time they start to make progress. And the 1000th time they finally get the hang of it. And when they make it big on the 10,000th try, they will know your encouragement helped carry them through the first 9,999 tries.
Great things have humble beginnings, but not without nourishment.
