Practice
Memory feats centred around numbers can be performed by experts who have learned a 'vocabulary' of at least 1 image for every 1 and 2 digit numbers which can be combined to form narratives. To learn a vocabulary of 3 digit numbers is harder because for each extra digit 10 times more images need to be learned, but many mnemonists use a set of 1000 images. Combination of images into a narrative is easier to do rapidly than is forming a coherent, grammatical sentence. This pre-memorisation and practice at forming images reduces the time required to think up a good imaginary object and create a strong memorable impression of it. The best words for this purpose are usually nouns, especially those for distinctive objects which make a strong impression on a variety of senses (e.g. a "Lime" for 53, its taste, its smell, its colour and even its texture are distinctive) or which move (like an "arrow" for 4). For basic proficiency a large vocabulary of image words isn't really necessary since, when the table above is reliably learned, it is easy to form your own words ad hoc.
Memorization of base set is much easier using Anki flashcards.

Famous quotes containing the word practice:
“No exile at the South Pole or on the summit of Mont Blanc separates us more effectively from others than the practice of a hidden vice.”
—Marcel Proust (18711922)
“The astonishment of life, is, the absence of any appearance of reconciliation between the theory and the practice of life.”
—Ralph Waldo Emerson (18031882)
“Fine art, that exists for itself alone, is art in a final state of impotence. If nobody, including the artist, acknowledges art as a means of knowing the world, then art is relegated to a kind of rumpus room of the mind and the irresponsibility of the artist and the irrelevance of art to actual living becomes part and parcel of the practice of art.”
—Angela Carter (19401992)
