Stop fucking procrastinating and start building that website you've been meaning to make.

Programmer? Close the browser, turn off IM, open your favourite editor, and get typing. Not a coder? Tumblr or WordPress will give you your own blog in minutes, for free. The most important thing is to get started.

The next most important thing is to keep going. The classic book on being in the zone is Flow by Mihaly Csikszentmihalyi, but it's not a step-by-step guide.
