Email is so key to every other aspect of one's online life I think it's best to pay special attention to its security. Use a good strong password (doesn't have to have special characters or numbers or anything, just has to be long and random. I use this to generate passwords currently:

And if your email service offers it, use two factor authentication (Gmail does), this makes it almost impossible to hack your email. In Gmail's case if you access your email from a new computer/location it sends you a text message (to a phone # you've previously setup and verified) with a response code that you have to enter. So even if some guy in India figures out your password it's still useless unless they can hijack your phone at the same time.
