I know this may seem a very obvious and basic statement. Planning helps us to see things in better perspective. It also helps to formulate ideas in our minds, and help the process of attraction.
Essentially, until we have actually written our goals and desires down, we have not fully committed to them in our deepest subconscious. I know this may sound almost upfront, but at least, give it a go. I can assure you these principles do actually work. They have been proven time and time again.
To best explain this, consider the following scenario-
You are thinking that you want to do something- you have an image in your mind of a project or a desire, and even though you know you have the right to it, you also have this very slight feeling that you are not certain you have what it takes to get it. Please please, get rid of this uncertainty. This is what kills dreams and effectively erases all the other good you may have created towards your initial desire. You see, even if you are not sure how you will get to where you want to be, you need to actually believe (make that Know) you will get what you want. I actually liken this to driving on a long journey at night. You know you will reach your destination, but the headlights only show up the immediate road ahead for a hundred metres or so, not the whole 800 kilometre journey!
In following on from this, you can then better prepare yourself for each phase, and recognise that as you go along, the unclear aspects will clear up for you. To use another example, when the first Boeing 747 was designed, the engine technology to lift it off the ground did not yet exist. However, the company management made the decision to actually go ahead, and start production of the aircraft. By the time they were ready, the engine design had become available.
Hence, for the above reasons I am a form advocate of writing down my goals, as well as displaying my desires in pictures. You can do what ever you feel most comfortable with. These concepts are also explained well in the Laws of the Universe program.
