You can do it. That's my point. Yes it takes time. Yes it takes patience. Yes it takes practice. Your brain is an incredible machine capable of so many things, much more by far than a computer. Computers are chunks of silicon. They do basic addition. They just do it so much quicker is all. Yours is superior. Keep it exercised.

I do keep a cheat sheet of clues. Things that I write to remind me of the actual phrase, but I rarely need it. Make a point to memorize 10 a week. Custom photo screensavers (I use jpeg Saver 5.3 by Goat 1000) are great for flash cards. I find writing it out to be the best way to learn, but reading is my second, and listening is third (but rather poor considering I lose focus and miss bits). Try to learn how you learn best and exploit that. I used to have an old braintest that was incredibly accurate. It would tell you whether you were more inclined for audio or visual learning. It also defined your brains inclination to be left hemispheric or right hemispheric in its dominance. It was called brainworks. I think it ran on windows 95. For sure Windows 98SE.

Honestly, a lot of the ones I ended up needing to lookup or reset were the ones that are restricted with a maximum length and I cant use an entire phrase. That just jambs up my plumbing, if you know what I mean.
