It doesn't matter what goals you set in business, life, or otherwise. You won't experience elevated levels of success until you accept a few things.
1) "Get rich quick" and "overnight success" are fictional.
2) Discipline and sacrifice will be your best friends; not in the beginning, but you'll see them as such in hindsight.
3) Leadership qualities are essential to your success (and your sanity). (Start by leading yourself in the right direction, then you can move on to leading others.)
If you are serious in your approach, no matter the objective, keeping these few things in mind will accelerate your success.
