Not that long ago, having a password that was just 8 characters long and just a single word was commonplace and considered by many as an acceptable level of security. Today however, using a single word or name, or using a word with a single digit or sequential number at the end, is just asking for trouble.
You’re probably thinking right now “Oh, but this doesn’t apply to me, no one would want to get into my email account, there’s nothing important in there”. The reality is: If you have an email account, at some point someone ( or more likely, some automated bot ) will try to gain access to your account.
In most cases (but not all) they aren’t trying to access your account in order to gain access to your personal data. More often than not it will be an automated bot which will try out millions of passwords until it succeeds. It will then use your account to send out a flood of spam, which will very likely get your email account blacklisted by one of more of the many spam blacklists around the world.
We realize that having a different password for every online account you use is impractical for most of us and having a completely random 15 character password with upper and lower case letters, numbers and symbols is next to impossible to remember. However it is possible to come up with memorable passwords that are hard for a bot to break. And by organizing your accounts into a few groups, each with a different password, can also make things easier.

Which ( if those were your words ) would be memorable, but also secure.
