Repeat this after each decision you want to make: "I can't lose - regardless of the outcome of the decision I make. I look forward to the opportunities for learning and growing that either choice gives me."
Do your homework in advance. Answer: Who can I talk to? Where can I get information to help me? What else can I do to learn as much as I can about either choice?
Do some soul searching. How does each option align with my core values? My priorities?
Trust your intuition. Listen to your gut after you do the other three steps.
