Most people can manifest the small things quickly. This is because they do not have any resistance around the small things, and because they don't think thoughts that contradict them. When it comes to the bigger things, however, people often emit thoughts of doubt or worry that contradict those bigger things. This is the only difference in terms of the time it takes for something to manifest.
Nothing is too big or too small for the Universe.
~From The Secret Daily Teachings by Rhonda Byrne
