As we grow, what is important to us changes. These changes sometimes manifest in "existential crises" such as midlife crises. The way to resolve an existential crisis is to redefine what is important to you. This allows you to focus and create something new. This can be done through a "rite of passage"- or consciously changing what your life is about.
Then you can attract the thing you intend to yourself. This is what The Secret and Law of Attraction talk about.
Once your intention is focused, you need discipline. You have to hold that focus long enough to for it to manifest. If you let your mind and intention go all over the place, you will create random things for ourselves. By the time the things that you intended presents itself, you are onto something else and often do not even recognize it.
Discipline allows us to work with our intention long enough to unfold it. This is illustrated through a metaphor of shooting arrows. If you shoot your arrows in the same direction, it takes you further and further toward your goal. If you shoot your arrows in all different directions, they are not able to be as focused and effective.
So take aim and keep shooting your arrows until the thing you intended presents itself. Many people give up or get distracted right before what they want appears. Focus and discipline.
