Knowledge speaks, but wisdom listens.
Knowledge is what we learn through the years, it is how we understand our world. Some may say that knowledge is in fact useless theory; you might have two PHD degrees and still be educated fool when it comes to real world life. Wisdom is the ability to put knowledge to work, or to use it, the intelligent application of learning. A person might have considerable knowledge but not know how to use it because of lacking wisdom. The experiences you have in your life will be converted into wisdom and that will provide you growth if you learn from them.
