Mr. Gurdjieff said that everything, can be seen in a single day. Your weaknesses, your strengths. It is all there. You just need to be conscious enough.
Acceptance will also be one of the skills to learn on your journey, because without it, you cannot go forward, acceptance is perhaps the most important ingredient in the new self you are building.
The threshold you will reach, as Mr. Gurdjieff said, "After long and prolonged efforts", is that you will achieve the quiet intensity that is required to work and overcome your weaknesses. Until that point is reached, you will be nothing but excuses.
The actual reality is, that you will not change, unless..... You go through the laborious taks of observing yourself, until you know how you work as a mechanism. Then you will reach the threshold of the next stage.
