I find I am most scared of the unknown or unfamiliar. Get comfortable with GitHub. CodeSchool has an awesome course entitled "Try Git" for free. It teaches you the basics in a very practical and immediately applicable manner. The "Advice" box to the right of the tutorial explains the vocabulary used within GitHub.
As you progress through the tutorial, you recognize you are starting to understand what "version control" means and most importantly, how to use it.
While Git is social (sharable), for an independent developer it is often just you, or just me. I don't want to be stuck in my house at a desk all day long. What if its nice outside? What if an awesome coffee shop/cafe just opened down the road? What if I'm feeling lazy and want to work from the couch? GitHub makes that super easy! I can download my entire project in a .zip and work away.
Your new ease of mobility can take you anywhere! The "home office" isn't so limited anymore. So, what do you think? Where would you find yourself with this new freedom and flexibility??
