Most of our decisions lie in that grey area, and barely ever are they clearly defined. We tend to overthink things, to find reasons for and reasons against, and we take the option with the more reasons, sometimes at the cost of ignoring our instincts. In the end, it is fear that stops us; the fear that going against the grain, against all reason will lead us somewhere worse than where we are. We know deep down that there is a chance that it could lead to something better, but we are too afraid to take the chance, especially as so many things in life are constantly in flux. We are afraid of getting there and losing what we wanted so much.
Often we'll meet someone or read something where a person did not take the chance that they so badly wanted and ended up regretting that decision for the rest of their lives. There is much wisdom in words saying that you will regret what you didn't do much more than the things that you did do. But humans are not so trusting creatures, and we are wary of life, even when we want to believe that it can turn out for the best.
So, take a chance on me, and I'll take a chance on you. Dispel the fear, don't weigh up the pros and cons, just follow your instinct. We're instinctual creatures, and you'll be surprised at how often your intuition is correct. Next time, take a chance on that stranger whose eye you meet, or that person you shared a smile with. You never know, after crossing that bridge of sighs, upon which you swayed precariously, unsure of yourself, you may find yourself in a place where the grass is really greener. You may find that the world not only is not black and white, but is in fact made up of splashes of colour. What was once scary may no longer hold any fear at all.
