Manifestation is about doing everything possible to achieve your goals and facing reality without any doubt. It is not about waiting for the outcome of your decision. Of course, many people wait for the different things that may come after they take a step because they are afraid of failure. But, if you keep assuming and do nothing, you will not achieve your goals in life.
To achieve a successful manifestation, the first thing you must do is to empty your preconceptions. Don't formulate things in your mind that you can't do it or that you don't have the power to achieve what you want. Preconceived ideas about manifestation are like not trying to fix the things that prevent you from turning your vision into reality.
