I have often stated that the biggest competitor to defeat is yourself. Meaning the inner voice that speaks to you and either tempts you to sit on your hands when decisive action is required or encourages you to chicken out when a bold move is required and many more in between.
Many times in our careers we are faced with challenges, some much bigger than we ever imagined but in those times don’t let the enemy be your lack of resolve or courage to the do the right thing.
Remember that you are the sum of your past experiences and go forward knowing that decisions you make will not always be perfect and that you survive.
Get in to the mindset that you are learning, evolving and becoming better and that one mistake will not finish you or make you. Take this actions and you will be less vulnerable to and from the enemy within.
