Have you defined what you want of life?
Knowing what you want is like going on a road trip. To reach the destination you must map out a route. Of course, like any great road trip, there will be detours along the way, but these won't throw you too far off track if you have a desired end point in mind.
So, the first step is discovering what means the most to you.
Isolate your wants, refine them and set priorities go achieve.
