We all have ideas. Ideas are immortal. They last forever.

What doesn’t last forever is inspiration. Inspiration is like fresh fruit or milk: it has an expiration date.

If you want to do something, you’ve got to do it now. You can’t put it on a shelf and wait two months to get around to it. You can’t just say you’ll do it later. Later, you won’t be pumped up about it anymore.

If you’re inspired on a Friday, swear off the weekend and dive into the project. When you’re high on inspiration, you can get two weeks of work done in twenty-four hours. Inspiration is a time machine in that way.

Inspiration is a magical thing, a productivity multiplier, a motivator. But it won’t wait for you. inspiration is a now thing. If it grabs you, grab it right back and put it to work.

The inspirational words above come from the book Rework by Jason Fried and David Heinemeier, the founders of 37signals.

If you don’t own it, you should.
