When choosing a password, you should avoid using:
• passwords based on personal information that can be obtained via social engineering tactics;
• passwords based on a word with some letters replaced by similar-looking symbols; for example: p@ssw0rd, 1l0v3y0u. This is quite a common practice, and the hackers are well aware of it;
• simple word or phrase, combined with the current or a recent year; for example: 2014pass; new2015.
One method to create a strong password that you can remember is to use a so-called "passphrase" -- a string that consists of multiple words; it is strongly recommended that it includes other symbols and/or digits too. Another popular option is to use randomly-generated passwords, and store them in a password-manager software.

Be sure not to share your password with anyone. Sending login credentials via e-mail, or an instant messenger that does not encrypt the data, is considered unsafe.
