quick easy way to generate your own very secure passwords for your crypto wallet(s)

...that you CAN remember w/o writing down! Not sure who originated the idea but hear is the method, along with my little twist:

Use a memorable line from a favorite song. Take the first two letters of each word and alternate the upper/lower cases for EVERY word, however IF it is a single-letter word just always make those letters either upper OR lower case. Done with it... now, IF you remember that one and only phone # your family EVER had while you were growing up (sorry gen-x er's and beyond), just place one two or three of the last four digits in the front and the remaining digit(s) behind that crazy mix of upper-and lower-case letters you got from one of your favorite songs...

Example: Line from Janeys got a gun: "...She had to take him down easy and put a bullet in his back.."
First Phone # last 4 digits 1234
