I agree with you completely, with what you say on detachment. Lack of detachment, and agree it is not so easy to be detached about something you deem important, causes stress and brings anxiety and fears, all of which work against the law of attraction. We all know the story about the person who planted a seed, and every few minutes turned the ground to see if it was growing.
What is it that most people desire? If you analyze your desires and goals, and reach the “root level” you will find that what you really want is a sense of happiness and security. Everything that you desire to accomplish or do is actually motivated by the desire to gain happiness and security, be it money, a house, a car, a new job, love or losing weight.
Under happiness and security you can position, inner peace, harmony, love, health and a state free of stress, anxieties and fears.
Too often, people devote a lot of time and effort getting something that in the end does not bring them the happiness or security they anticipate. Ask yourself what would bring you a sense of happiness and security? Look at each goal, and think earnestly and sincerely, if it would bring the coveted happiness and security you desire. If it does not, why not find some other, better goal?
The law of attraction works, but reading a book or watching a movie or video will not make it work. You need to have a strong desire, and be willing to do mentally and physically whatever it requires to get it. You need to keep an open mind to opportunities, new ideas and intuition.
You also need to be certain on a conscious and subconscious levels that attaining your goal is really important and useful, and would bring more happiness and security into your life, on the inner and material levels. Doubts and uncertainty about your goals can neutralize your efforts.
