★ No More Excuses: Start Your Side Project Already

"My favorite way to test an idea for a project is by setting up a pre-launch mailing list. It takes less than a day to write, build, and hook up a “Coming Soon” page with a mailing list. I include a little blurb about the project (what problem it’ll solve) and then build in a single call to action: Sign up if you’re interested. Chances are, that if 100 or more people sign up, your idea has enough merit to move forward."
