Allow yourself the luxury of not knowing and releasing yourself from the responsibility of a sense of certainty & manual control of your world is an important ingredient for personal change. The problem with knowing everything and having it all down pat means that the plans you make are more likely to be disrupted.
Intent and assumption are quite different than the stance of knowing everything
Knowing everything is a reactive state conjured up to create a secure path of predictability and the other is the steady and detached permission of your intent to grow and create a desired outcome.
The self-talk of this might be something like; "I don’t know just how it’s going to happen - I am detached from the result, but I firmly believe this goal will now evolve!"

Deep down everyone is drawn towards people with intent, assumption and positive energy. If we can’t generate it within ourselves, we find someone to reflect it back to us. Similarly when you apply the power of intent and assumption positively to your goal and strategy it’s becomes very magnetic. Not only does it align and bridge your conscious mind with your unconscious, but it has the capacity to motivate and magnetise other people towards your goal

Hypnotists know that one of the quickest ways to hypnotize somebody who’s been hypnotized before, is to ask them to describe in detail the previous experience. The simple re-inhabiting of an experience can completely revivify it as if it already co-exists now.
Imagine what this kind of hypnotic home magic could be used for:

To envisage that your future has already happened - See in your mind's eye that you have accomplished your goal and how your life has changed,
To imagine the means to your goal, mentally rehearsing and nurturing the feeling, as if it’s already happened.
To earth-wire each achievable step and bring it to life using the electrical current and glue of your emotions.
To try in vain to remember just what it was, that were problems, now that the future is now and they no longer exist.
To think of all those things that you said you’d become way off in the future one day, NOW, and isn’t that something that was worthwhile NOW you are that.

Thoughts become your words, Your words become your actions,
Your actions become your habits, your habits become your character,
your character becomes your destiny... You think, therefore you are... your destiny.
Whenever you think someone witnesses . . . inside,
whenever you speak someone listens . . . inside,
whatever you do someone always notices . . . inside,
whatever habits you create someone will store . . . inside,
whatever character you create, you inhabit,
and there is always someone behind that . . . inside
Subsequently whatever destiny you have now created for yourself, there is always more . . . inside
