How to Memorize a Lot of Numbers

It was painful to make that transition. So my old card system probably shouldn't be called a system. It just takes so much time to get to the point where I can see the two card pair and instantly think of my image because I got so many pairs to keep in mind. For numbers, unless you memorize a 3000 number number number every day, you're not going to see all of your images. That's how I ensure I see each of my images at least once a day.
