Bridges That Only Go One Way Probably Need Burning
In your daily walk, you will encounter, and perhaps, befriend a lot of people. Some of those people require nothing from you and you require nothing from them and, if given time, a bridge of simple mutual enjoyment is built. Others will need things from you and you will find that you need things from them and both fulfill those needs through transaction of time and talent and another bridge of a different sort is built.
Then there are the one-way bridges.
How do you want to be defined? By one action? By some opinion that could evolve? By a mistake, regrettable only with hindsight? Or by the sum of your parts? Okay, do that for other people. Start the trend.
