Does the sight of a snake cause you to panic and make you want to run away as fast as possible? If so, it means that you are afraid of snakes. People are full of fears: fear of insects, weapons, heights, and so on. Horror movies are the ones that try to terrify viewers as much as possible. However, some fears make more sense than others: jumping from a plane in flight can make you paralyzed with fear - compensibile - but the fear of public speaking is not so logical - don't worry, you won't die. Fear obviously includes anxiety and this feeling can be emotionally very unpleasant.
"Only one thing makes a dream impossible: the fear of failure.
"When you stop having fear begin to enjoy."
