I believe fear is the ultimate betrayal to our true selves...it can lead us to overthink a decision, which can lead to analysis paralysis and often crazy decisions. Fear can cause us to put off or avoid some decisions, which often results in lost options and oftentimes even worse outcomes.
While you will never be able to cut mistakes out completely...by creating a solid action plan it will provide you with the structure to have faith in your own intelligence and expertise so you can make those important decisions and take control.
