Are you waiting to get started because you don't have a degree, don't know enough, or some well-established guru hasn't told you you're ready?
If so, you may be suffering from what I like to call the Myth of Permission.
You see, our culture has taught us that we have to get a degree and then work and slave for years, putting in long hours doing menial, thankless tasks until some glorious Expert looks down from his crystal mountain, points his wizened index finger and says, "You are worthy."
This, in short, is a crock. You don't need permission from someone on high in order to feel worthy. All you need to do is learn all you can about it, and then go out there and do it. Only then will you truly feel and be "worthy."
Remember, you don't need permission to be successful. You already are.
