Pick a word, favorite pet's name or something that's an easy go to, then start at 1 and just keep going up sequentially. At work we have to use 3 different types of characters and it has to be at least 8 characters long, so I chose a work-related word and I'm now up to number 39. So, you can start with Password1, then go to Password2, then 3 and so on. I sometimes forget what number I'm on but I'm always within one.
