Research has shown that our ability to defer gratification correlates directly with our eventual success in life. This was discovered by having a bunch of men in white coats give sweets to small children; which I have to admit, sounds kinda creepy.
What the researchers discovered is that the children tended to fall into one of two groups: the first would eat the sweet immediately. The second were prepared to wait before eating the first sweet, in order to be rewarded with a second sweet.
They then followed the children through life; again, creepy; and discovered that the people from the second group who had been willing to defer gratification as a child tended to do better in life as an adult than those from the first group.
So in order to help out, I've made the following video to give you a direct personal experience of developing patience. It's such an important lesson so be sure to watch the entire video in full, to make certain that you don't miss it:
