It's an important question to ask.
A year ago I didn't believe I could make a living working online. It wasn't because I didn't have the skills to do so. It was the fact that I didn't believe I could. They say "You miss 100% of the shots you don't take." It was until I made the first step that I realised the change starts with your mind. What can you do today that you were not capable of a year ago?
