Many people are stuck in a particular position in life simply because they feel that making a change would cause some measure of discomfort. To avoid the discomfort they linger in the existing state of affairs even though that causes discomfort as well. The sayings "Better the devil I know than the devil I don't." and "Don't jump from the frying pan into the fire." Express this sentiment.
Note the system of expectation at work here. When discomfort or pain is expected, the force works to keep you from making any change, even when the pain is imagined and may never take place.
To have a better understanding of desire, see it on an ascending scale, like a giant thermometer. At the bottom of the scale is zero, and at the top, one hundred.
When your desire is weak, near the bottom of the scale, it is unlikely that anything will motivate you to activate your will and accomplish the object of that desire. When your desire is near the top of the scale nothing can keep you from success in attaining that desire. To enhance desire, go to level and visualize the positive end result of what you desire to happen.
