Online marketing definitely starts from within and thus achieving exteriorly once you reach a certain level.
The vision starts within and then manifests into your reality.
Also, never let someone tell you to stay on your feet, be realistic or get a reality check when they comment on the rare likelihood of your success (in their mind) because really, there is not such thing as reality in that term.
Time and time again throughout history man has achieved the most remarkable things regardless of what there environment thought was good, bad, indifferent, weird or just plain outright not possible.
Hope that helps.
