In the beginning there is you.
First things, first. You don't have to know where to start; that's not the point. The point is to begin by placing one foot in front of the other; the answers will come to you along your journey.
The most important part is discerning what it is you want to tackle. Set a goal. Make it clear. It doesn't have to be a big one, but it needs to be apparent.
Welcome to my journey.
