That depends entirely on your existing programming.
If that previously mentioned martial artist weighed 400 pounds (approximately 180 kilos) and never worked out a day in his life before becoming a martial artist, it would have taken a lot more work to get to those 1000 repetitions. The first time, he would have gotten tired after 10 reps, the next time maybe after 20 and so on. Next, he would have to deal with the muscle aches because his body wasn’t ready to move like that any more than his nervous system was.
When he finally got to a 1000, he would have mastered a single move. Then it was time for the next move. Punch after punch, kick after kick, grapple after grapple. On and on, until he reached a new level on his road to complete mastery of the art.
At any time he could stop if he was content to be at the level he had achieved. Or he could keep going, continuing to mold his body and mind, becoming better and better every day through sheer determination and willpower.
As a mental artist, you have the same challenge. The martial artist’s nervous system is your subconscious. It is the part that will eventually remember the training and make it a part of your identity. The martial artist’s muscles and body are your conscious mind. It needs to learn how to deal with the new reality of what you are becoming.
The further removed your current state is from what you need the subliminals to turn you into, the more work is ahead of you. We don’t know where you are, or how often you force your conscious mind to step outside its comfort zone into the new reality you are building by taking action. So we can’t tell you how long it will take, only that it will likely be longer than one or even three months.
Answer this question for yourself:
Are you happy being a green belt, or do you want to keep going for the black belt and beyond?
Wow, this analogy really turned out better than I thought it would.
