If you would like to speed up the manifestation of something that you would like to attract, you need to do your best to stay happy. When you are feeling negative or anxious, this will be enough to hinder the manifestation to take place immediately. The more attached you are to something that you desire, the longer it may take since you are being too focused on it.
What you can do is to allow your energy to fill you up with positive vibes so that what you ask will be given to you. Listen to music that will fill your soul. Go out with people who will make you feel better. There are so many things that you can do that will help manifest the things that you want faster.
