Indecision comes from lack of clarity and confidence.
When you enhance your clarity and confidence, you become decisive.
Being decisive does not mean being reckless. It means being clear about what you want, and carrying out the necessary due diligence to decide.
Fear also creeps in when clarity, confidence are missing. So instead of wasting your energy on fear, invest it in due diligence.
Sitting on the fence is not an option; decide one way or the other and move on!
