I had the same problem myself. Yet again I would suggest to read the book Eat That Frog by Brian Tracy. This book teaches you a set of methods to improve your ability to get the right things done. It's available on O'Reilly Safari (where I read it) and from Amazon.

Full of practical advice. In the same vein, it's good to read all e-mails / blogs after lunch. Keeping IM, Twitter off till that also helps.

In a nutshell, the mind, like money, is an excellent servant, but a terrible master! Hope this helps.
