There are two things you can do to get a clear decision.
Trust your first decision – the one you made before the doubts claimed their head space. Your first decision is invariably the best one – even if at the time it seems to be illogical or not practical or way out of your depth. Trust.
The other option is to get three small pieces of paper. Write the word "yes" on one piece and fold it so that you cannot see the writing. Then write the word "no" on the second piece of paper and fold it in the same way. Then write your question on the third piece of paper and fold it in the same way.
Put all three pieces of paper in a mug.
Now take one of those folded pieces of paper in your left hand (don't peek) and hold your left hand closed over your heart. Close your eyes, clear your mind and wait. Notice whether your body wants to swing forward or backwards. Put the piece of paper down and remember how your body responded.
Do the same with the other two pieces of paper.
You will end up with two pieces of paper on one side, and one piece of paper on the other side. There is your decision.
Listen to your intuition and your body.
