I tell you from experinces that mind and brain have a lot power.
Your mindset has power when it comes to manifestion thing it only works If you think through who you want to be and what kind of life you should have this is like gps navigation once you have set your destination then solution how to get there will come in your mind soon you will be using little skills and knowledge resources you have to get there.
You need be strong in your mind If you not sure what you want you don't get nothing.
Another example: i had to do one difficult Job with low money but before i went to that Job i said myself, " it's low paid job and not easy but i will be best on this job i will do good and i Will do fast and i Will be very productive" and then it happens i was best on this Job and even when it was hard i managed easy way.
Need to give your mind strong directions and the rest of it your Brain will work out.
So your goal will be like building the house you start from the roof the roof is the goal and then you move down to the how to get there how to do it.
