Do you use weak passwords or the same one over and over again, maybe adding numbers to the end? Are you password fatigued?

We all know what a pain it is to keep track of the endless passwords in our lives. Sure, hacking is a big problem. Look at all of the sercurity breaches with major companies these days. It seems like everyday we are asked to create a new password or remember an old one. But, we also know it is important to use strong, unique passwords. 

However you end up using simple passwords that you can remember. You write the changed password in some book filled with pages of scribbled and crossed out logins. However, they are just too weak to be secure. You know better, but making a strong and unique password for each and every site and service is out of the question. Or is it?
