For as long a I can remember, people warn against having tunnel vision. They tell you to “gain a broader perspective”, “open your mind”, or “take in your surroundings”. In general, yes, those are very good things. I’ll always be the first one to take in the scenery and the last one to make a decision if I haven’t considered all the options. But I’ll tell you one thing I learned last weekend: sometimes tunnel vision isn’t such a bad thing. It can save your life when what’s going on around you is too much. I’m alive to prove it.
