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:
“She, too, would now swim down the river of matrimony with a beautiful name, and a handle to it, as the owner of a fine family property. Women’s rights was an excellent doctrine to preach, but for practice could not stand the strain of such temptation.”
—Anthony Trollope (1815–1882)
“When any practice has become the fixed rule of the society in which we live, it is always wise to adhere to that rule, unless it call upon us to do something that is actually wrong. One should not offend the prejudices of the world, even if one is quite sure that they are prejudices.”
—Anthony Trollope (1815–1882)
“It is not always possible to predict the response of a doting Jewish mother. Witness the occasion on which the late piano virtuoso Oscar Levant telephoned his mother with some important news. He had proposed to his beloved and been accepted. Replied Mother Levant: “Good, Oscar, I’m happy to hear it. But did you practice today?””
