1. Stick non-alpha characters in the middle of words. Not 31337 substitutions; additions. Now your dictionary word isn't a dictionary word anymore.

2. Use the first letter of each word in a phrase. Again, now it's easy to remember but not a dictionary word.

3. Find a way to customize the password for each site in such a way that you can remember the pattern. Use letters from the stock symbol, the dominant color, the domain name, or some other word you associate with that site. Boom - now your password is unique per site.
