You can't just tell a person healthy advice and expect to have them understand the scope and focus of such an idea, until they are ready to truly receive it in a deep place within themselves. There is a certain urge, a fire, an almost painful suffering sort of a rush, to want the most success for themselves, and the best and highest good possible for all involved or invoked into the goal.
It's never just you alone, going into your goals. So many other pieces and players are a part of your manifestation that once you begin the process, all these pieces keep coming up that make you want to quit, give up and throw in the towel. Sometimes words can't even describe what the Spirit hopes to assist with.
Remembering that manifestation is an intricate, involved process, is what is mostly required to get you through anything. As you manifest your desires, and the images of all parts come into play, make sure to write them down as if you are investigating something, trying to solve a puzzle, and you begin elaborating more and more on the theme until it becomes a living, breathing entity.
