I strongly agree to the opinion that self-help methods only work if you take responsibility and ownership for the results.
I'd say the only exception is Holosync, since it pushes you whether or not you believe it's going to work.

Of course, if you don't listen consistently, or if you refuse to take ownership for the feeling of overwehlm that may arise from time to time, then you might in the end make even Holosync fail, by not being persistent...

Cheers,
