I've always been intrigued by the subject of fear; specifically, why is it that some people are fearful of one thing or another while other people are seemingly fearless? Is it biological? Environmental? There is of course the "fight or flight" element which centers around fear. Some people will typically choose flight in dangerous or intimidating situations while other people would choose to fight.
Oftentimes, we fear certain things that we never even had any experience with; we are in fact conditioned to fear such things.
Fear is a necessary emotion as it helps us to prepare to defend ourselves against dangerous stimuli in the environment. However, fear can also be a hindrance if it prevents a person from pursuing goals and/or activities because of the fear of failure, ridicule and/or the ramifications or consequences of such activities.
