A few weeks ago I gave my friend Chase Jarvis 3 reasons why all workers — not just “creatives”! — should be showing their work:

1. Documenting your process helps your progress.
   Keeping track of what you’ve done helps you better see where you’ve been, where you are, and where you’re headed. It’s also a great way to hold yourself accountable — if you dedicate yourself to sharing a tiny bit of your process every day, you’re forced to actually do the work you should be doing.
    
2. Sharing your process reaps the benefits of self-promotion without the icky feelings.
   People are often just as interested in how you work as much as the work itself. By sharing your process, you invite people to not only get to know your work, but get to know you — and that can lead to new clients, new projects, and all sorts of other opportunities.
    
3. Building an audience for what you do creates a valuable feedback loop.
   Christopher Hitchens said the best thing about putting out a book is that it’s a “free education that goes on for a lifetime.” As you gain fans and followers by sharing your work, they will, in turn, share with you. Even when the feedback is bad, it can lead you down new paths.
    

That’s a short version of the why. The book will teach you how.
