Alex Tew created a website that encourages you to calm down and slow down. Just sit in front of your computer and do nothing for two minutes but listen to the sound of waves splashing. No, don't touch your mouse or keyboard or you'll have to start over. Tew writes:

I had been thinking how we spend every waking minute of the day with access to an unlimited supply of information, to the point of information overload. i also read somewhere that there is evidence that our brains are being re-wired by the internet, because we get a little dopamine kick every time we check our e-mail or Twitter or Facebook and there’s a new update. So we’re all developing a bit of ADD. which is probably not great in terms of being productive.

It took me three tries.
