Hi there Schealer, first let me say I don't claim to be a leader in this field by any means.
What I do know is that "the why" is vital and will give you the passion.
I believe the sub-conscious part of the mind works like a heat seeking missile - it doesn't know the difference between what is true and what is not - what will bring good results and what will bring bad ones.
It will simply serve you by bringing about your most dominant thoughts.
For example, I used to feel really good when I imagined or visualised every day opening big patio doors and just walking the dogs through them into private beautiful grounds of parkland filled with trees and a stream (no putting collars and leads on them all - no putting them into dog cages in the car and driving to the local woodland where we would meet other dogs - and no getting dirty everytime I picked them up to put back in the car after they had had their run about)
Of course the parkland wasn't just for the dogs to enjoy - this was just what I imagined each day.
I also visualized a library room - the big reason why was to keep a library of "the good Books" I often mention. These will always be recommended to future generations so they won't have to wait until they are 40 as I did to discover all the amazing success principles.
I think one of the greatest fears is the fear of success and also the fear of loss.
Someone once said to me that once a persons mind is expanded by a dream, there's no turning back and there was a time, after all the excitement of discovering that I could achieve what I truly desired, when I wished I could go back to the ignorance of not knowing what I had discovered
All the doubts and fears would come flooding in - but I couldn't turn back for I knew too much then. Yet it seemed like the only way forward was to climb an impossible mountain (which I later discovered was my lack of belief in myself.)
Going to work, doing the same things day in - day out,for years had created a deep rut in my life which had worn so deep that I couldn't see the opportunities that were available over the sides.
I was like a hamster running round and around on it's wheel, chasing it's tail, expecting a different result.
Then I read the following words by Napoleon Hill "Any idea, plan, or purpose may be placed in the mind through repetition of thought. Hold a picture of yourself long and steadily enough in your mind's eye, and you will be drawn toward it. Man, alone, has the power to transform his thoughts into physical reality; man, alone, can dream and make his dreams come true."
Personally, I work on one dream at a time - I believe this creates a laser focus.
The more you visualize the more you realize and actualize - I believe this creates and builds belief.
Feeling grateful every day for everything good in life is a priceless exercise
If I become aware of any doubts I usually think about what I am grateful for.
Being quiet in meditation allows us to change our map of reality - we become more confident and as our cluttered mind becomes clearer, creative ideas have room to surface.
I hope this helps and wish you an abundance of peace and happiness
P.S. I wasn't quite sure of your following question sorry:-
"Also, how do you handle desires that are not materialistic - for example, having easier call nights or days - without it impacting your revenue stream etc)"
