Iagree with Meghan that many times we are afraid, but i think more than what we of afraid of seeing we are more of making change. Its not so much the change, or the start. Rather, we are afraid of the process. That is often why so many people bail in the middle of diets, projects, and stay stuck half way through. A good friend told me that. But once, we start to see the otherside we see the motivation, and sometimes thats all we need for a little change.
More than that though, I think we also often lack the open mind, the knowledge, and the diligence to change. All three are critical and without them, any "change" is simply luck and will probably revert back.
I think most people can agree on love, its just that we are afraid to take action for it.
