I think a good deal of confusion can be cleared away if you stop for a moment and apply some realistic standards. In order for self-help to work, you need to know a few things with some certainty:
Who am I today?
Where am I heading?
What do I want my future to look like?
These are not abstract or airy-fairy questions. At bottom, self-help exists to offer a new direction. For that to happen, the old has to give way to the new. Old habits and conditioning need to be transformed, and that isn't possible except at the level of consciousness. "Who am I?" really means "How do I see myself?" Self-help doesn't work because you found a wise, all-knowing teacher or a quick fix for a tough problem.
Self-help works if it wakes you up, either a little or a lot. The best way to wake up is to know who you are, where you're going and what the future could be. Present reality is the foundation. The future is a vision open to all possibilities.
The enemy of self-help is whatever closes off your consciousness and narrows your vision. Skeptical friends and people around you who are stuck in various ways are no help. A family that wants you to stay safe and secure in your box is no help. The reason the human potential got off the ground is that the yearning to break free is innate in everyone, yet society is arranged to resist and quash that impulse.
Once you see the gap between who you are today and what you could be—I mean, really see it, with your heart as well as your brain—awareness will begin to expand. Nothing can stop it, in fact, because there is a hidden dimension to self-help. On the surface, you seem to be improving the self you know, the one that gets depressed, overeats or gets entangled in a bitter divorce.
But at a deeper level, you are uncovering your true self. This self is at peace; it lives in silence, and its greatest joy lies in simply being. The true self is your source. At some point, you find that self-help isn't really about self-improvement. It's about self-discovery. When that stage is reached, much of the confusion and frustration that now exists will change. With a clear purpose in mind, seekers can use self-help as a tool to reach their real goal, which is liberation in fulfillment.
