Just because something that you want, wish or hope to do is huge should never be a reason to not even take the first step. It is good to be clear on what is it that you are trying to accomplish. Once that is done, give a considerable amount of time to think of the easiest step forward that you can take to move it along. It might not be perfect or even the right thing to do but usually, if it is that already then you have probably taken too much time in doing so. For most people, thinking too much will result in them not doing anything about it and that is something that you would not want, I hope. As long as you follow the small easy step forward with another and another, keep going until you reach your goal, you will ultimately find success.
