Quote from A Course in Miracles Text Chapter 31 - THE FINAL VISION.

T-31.IV.7. Think not that happiness is ever found by following a road away from it. 2 This makes no sense, and cannot be the way. 3 To you who seem to find this course to be too difficult to learn, let me repeat that to achieve a goal you must proceed in its direction, not away from it. 4 And every road that leads the other way will not advance the purpose to be found. 5 If this be difficult to understand, then is this course impossible to learn. 6 But only then. 7 For otherwise, it is a simple teaching in the obvious.
