The negative things about this would be, if your changing your password so many times and you have so much you might  forget it because you will have other passwords in your head, so make sure you write it down every time and it is something simple. 

The positive things about this would mean this is a safe way to have your password, and if you do write it down then you are good and you should be fine, but it really helps to change your password regularly in-case anyone knows it or try and gets on to it.
