Rules change over time. We adjust them to suit ourselves and to justify other people’s behaviour. We know we shouldn’t do it, but we do. It’s easier sometimes.
But certain rules should never change once you establish them. If you set the rule for example that you will not settle for less because you are worth it, don’t change. It might take time but the right person will come along. I have absolute faith in that.
Even if he (or she) is late.
