memorizing steemit password is not something advisable and it is not easy to have all those combined things stored in the human memory.This password was intentionally created that way so that it would not be easy for hackers to hack your account or people around you to easily memorise and steal your account. it is made up of mixed letters and figures both in upper and lowercase.memorising your password wont be easy and i will say you should save it in a safe place like drop box, your email ,or even your secret diary(you need to make sure you write it well without writting upper case for lower case and missing any figure) and also,it must be handled with care because once password is lost,it cant be recorvered. However, i have a book i read sometimes,its called MEMORY by Richard Thompson, you can take a look and read but not advicing to memorize your steemit password.you might forget it...
