Learning is a great key to success. If you stop learning, you start failing.
You cannot bake bread if you do not know how to do it. You cannot prepare a good salad if you do not know how to do it. You cannot run a good blog or website if you do not know how to do it.
The way to know how to do anything is to learn. To succeed in life, you have to keep learning how to better do what you are doing; how to set goals and achieve them; how to turn failure to success; how to turn stumbling-blocks into stepping-stones; how to be positive etc.
Therefore, make learning a life-long commitment.
