When utilized properly, fear can keep us alive, alerting us to dangerous situations and risky behaviors. Truth be told, fear is actually a survival mechanism—those who have no fear aren't aware that touching that poisonous spider will kill them. But fear can also be crippling as well, hindering your every thought from turning into a positive action, creating a sinkhole for your soul. When your fear takes over and stops being helpful, it turns into your own worst enemy, one that you must conquer from within.
