Everyone else is so right.. the first step is coming here - there you don't need to think about where to start - YOU'VE STARTED!
Remember, jump in on all the challenges and if you do have a "slip", we're all here for each other.. Share all your accomplishments and weak moments. It will give you the strength and encouragement to keep going! We're all here for the same goal and will accomplish it together!
Best of Luck!
