Most of the valuable work we do involves fear.
Taking a step forward to make a difference or move things forward involves some calculated risk. Where there is risk you will always find fear. The brave, successful and admirable who make things happen are not fearless. They just decide to deal with the emotion.
They look their fear in the eye and are brave enough to say what they are scared of... like losing, being exposed, sounding stupid, looking silly, missing out, being hurt or not succeeding. This gives fear a focus that can be managed or mitigated, rather than a reason not to act.
Alternatively, we focus on fear as a generic label and amplify its existence. An unsurmountable set of circumstances that get anaesthetised with excuses for inaction. Like a lack of time, money, position, motivation or means to do the work that matters and makes a difference.
The feelings associated with fear are real. Using them as a reason to prevent progress is a fallacy. Taking the step forward is rarely easy. Rehearsing your fears only makes that step harder to take.
