Belief, Truth, and Knowledge

What is the difference between knowledge, truth, and belief? In my opinion, which it is a funny thing for one to give their opinion on such a subject, is that all three of these help shape our minds. We only know the things that we believe and believe the things we learn as true. In learning truth, we think about what really is true. And in learning truth, we can begin to doubt what we already believed to be true. See how all three connect? The main thing here is truth; and what really is true against what we just think is true. Also, how to we come to getting at the truth. To know something, you have to believe it is true. And to learn the truth, we have only but to doubt the things that we think are true. The key here is an open mind.
