Writing Clears Your Mind

That's a first benefit.

The second is that once you commit to something, you can do it for a long period. Seth Godin writes a blog post daily.

This in turn, helps you create a habit, and it gives you back so many things - ideas for other projects, direction and connection.

And if you are lucky, you might get permission from people to keep sending good stuffs and then you can practically earn a living from your audience.

You don't have to write - simply create something each day. It can be a design, code, connection, or even a physical thing. Just keep creating.
