Problems are like microbial organisms. They hardly need a conducive climate in order to keep on growing. Give them just the smallest opportunity and they will replicate. Plus, of course, they feed on themselves. All you have to do is have one and somehow, it starts magnetically attracting others to it. 'The darkest hour,' we are informed, 'is always just before the dawn.'. You have free choice. Nobody can force you. And none of us should ever feel that there is any shame in changing your mind. The reason for carrying on should only ever be positive. We should proceed when we believe that we are doing the right thing, even if it isn't a particularly easy thing to do.
