A Fairly secure Password

You need at least 6 words.  A phrase you like, the chapter title of a book, some witty or funny saying, something you KNOW by heart.  Easy to remember.  Or, you already know it.  You also need some replacement rules. How you ALWAYS replace certain letters with numbers or symbols.  Rules that you ALWAYS use, so you can remember them.
As an example, rules can be:

    Letter             Replacement
----------------------------------------------------------
       o                         0   (zero)
       i                          |   (vertical bar)
       e                         3
       s                         $
       w                       \/\/ 
       m                       /\/\

       l ("ell")               1   (#1)
       x                         ×  (multiply sign)

And so forth.

Let's imagine the phrase you chose is:
you can easily make good secure passwords

You take the first letter from each word in the phrase:
  ycemgsp

You next use your replacement rules on these characters:
  yc3/\/\g$p

To make it better, you capitalize every alternate letter, giving:

Yc3/\/\G$p

THAT is a password that is pretty damned secure. It cannot be guessed.
If you chose a phrase of six or more words that you already KNOW, then all you have to remember is the replacement rules you created.  If you make those rules easy to remember, (Except for the "w" and "m", the rules above are easy to remember), then you have a secure password without too much trouble, THAT YOU CAN REMEMBER.

This sounds like a lot of work.  It really is not.  It takes a lot of words to explain it in detail.  ALSO, you only have to do this VERY infrequently.  For some passwords, only once every couple of years or so.  It is not as bad as coming up with new passwords every couple of months. 

Try it.  See how it works out.  Leave a comment.
Thanks.
