Faces of Fear: Doubt
The more limitations you set for yourself, the more limited you are.
I would not say we are all limitless; by the simple virtue and fact that we currently reside within physical bodies, we have certain limits. The key is to make ourselves as limitless as we can while occupying our current form.
Just a moment ago, I wanted to get two things done at once (such that I would have had to have been in two different places at once). I could not, so I had to instead prioritize and compromise. That would be an example of a real limit.
When I look at the problems plaguing the world today, I feel powerless to make the changes I want to see in the world because I am just one man. That is an artificial limit, until such a time that I have done everything I can to prove otherwise.
Doubt instills artificial limits, which we all too often fail to question and inspect properly.
Every great figure throughout history, every heroic visionary, every brave revolutionary wrestled with the fiercest doubts at some point or another in his or her journey. Every one of them would have never been had they given in to the idea of their own limitations.
Doubt will make a return when we get to the proactive part, the actionable solutions for all of this. For now, it remains as brief as this because - when compared to the other so-called 'faces' of Fear - it really is fairly elementary in essence.
