I like Ali's thought of the inner voice. Trust it as it is usually right.
Once you reach your decision point, be sure to follow through w/out wavering. Be committed to your choice and you'll be fine. Don't allow yourself to 2nd guess your choice once it is made.
If you aren't ready to make a firm decision at this point, then don't. Why rush it if you aren't sure. On the other hand, if it is time, then it is time.
