One thing to remember when you use the afformations is that you have to ask the questions seriously. You can't just mindlessly repeat a few afformations and expect to get results. The questions have to be asked as if you are genuinely looking for the answer. Otherwise it won't work.

When I wrote to Noah St. John for some practical advice, he recommended spending between 5-15 minutes every day meditating on the afformations. They must be done every day until the effect takes hold. The subconscious mind operates by asking questions. I may be wrong about this, but I suspect that after enough conscious practice, the brain will begin to ask itself the same questions automatically on a subconscious level. If that happens, then the changes would start to happen automatically and the results would become self-reinforcing with or without your having to put conscious effort into it.
