     Do you know what Fear and Faith have in common? Fear believes in a negative future. Faith

believes in a positive future. Both believe in something that has not yet happened. So I ask you,

if neither the positive

nor negative future has happened yet then why not choose to believe in the positive future?

     I believe during these challenging times we have a choice between two roads: the positive road

and the negative road. And our bus can't be on two roads at the same time. So we have to make a

choice and this choice determines our belief about the future and the attitude and actions we bring to

the present.

     I'm not saying we shouldn't have any fear. There are times when fear is a gift. A healthy dose(剂量)

of fear causes us to examine our situation and plan for the future. It moves us to smell the cheese and

expect change. When used wisely it allows us to manage risk and make better decisions. Some fear is

good.

      However, what I have observed lately is a supersized, huge dose of fear that is spreading the hearts

and minds of far too many people. This oversized fear is causing leaders and their organizations to either

act unreasonably or to not act at all. They are either hurrying in a million different directions because

of fear.

 In both cases, fear is leading them to take the negative road to failure.

     The answer is the positive road paved (铺满) with faith and a belief that your best days are not

behind you but ahead of you. With this belief you make the right choices and actions today that will

create your positive future tomorrow. You stay calm, focused and committed to your purpose. You

look for ways to save money and cut costs without making unreasonable fear-based decisions that

sacrifice your future success. You identify opportunities in the midst of the challenges and you focus

on solutions instead of problems.

    Your faith and belief in a positive future leads to powerful actions today. The future has not happened

yet and you have a say in what it looks like by the way you think and act. Fear or Faith. The choice is

yours.
