Don't use a blowtorch to light your cigar. You know the problem. It's the same as swatting a fly with a sledgehammer. I prefer to open the door and let it out. But that's another issue. The problem I want to focus on now is that of using the wrong tool for a job, and one that's far too sweeping or powerful for the precise need you have.

Consider the common problem of anxiety. Any focused form of anxiety typically arises out of a belief or expectation that one or more of our desires will not be satisfied. You want to get the deal or ace the exam and you're afraid you won't. You hope to win the new client or get a standing ovation, and worry that you'll fail. 

We aim for something high, and fear the world may give us only something low. That's what I like to call the disappointment gap. It's possible that what happens will be greatly disappointing. So we get nervous or grow anxious.

Some extremist philosophers historically have said, "Shed all your beliefs, and you'll shed your anxiety." Others haver counseled, "Get rid of all desires, and you'll get rid of your anxiety." But either of those strategies is lighting your cigar with a blowtorch. It's not necessary. It's going too far. And it's dangerous in its own way.

The middle path is simpler. I think you're in trouble if you believe too much or believe too little. I'm convinced that it's a problem if you desire too much or desire too little. The key is having the right beliefs and the right desires, and using your mind properly in your governance of your beliefs, your desires, and your actions. That advice won't fit easily onto a bumper sticker. But neither will your life.

And the more general advice here is in fact simple. Use the right tool for the right job. And you can slap that one on the bumper with so much glue that it will take a blowtorch to get it off.
