You can only go so far as you allow yourself to go. That said, you can't just sit back and do nothing. You must put in the mental and physical effort to attain what you want without getting stuck on "Must Have, NOW."
And your goals are nothing near as "unreachable" as mine, yet I KNOW I will achieve them. I have no freaking clue -how- exactly, but I'm not too worried about that part.
If my desire is strong enough and my efforts are backing it up, that's all I need.
