Our lessons come in many shapes and forms; as many as we have need of them and for as long! We don't always know or understand the length of them or the cost of them either, but they will endure for all time after they have been learned! So when we start to get tired of our endurance rate, we can simply remember that the cost of learning comes with many bridges burning! And our times will flow on by until we understand fully why we came here. And when we finally ascend, we will totally know why we had to go through all of the heartache for the promise of tomorrow!
