In general, I’ve noticed, worrying about things is harder than actually experiencing those things.
There are two basic reasons as far as I can tell.
For the first part, most things don’t turn out to be as hard as we tend to think while we are still in worry mode. Almost by definition, once we start worrying about something we assume the worst. And while sometimes it does come to pass, most times – by the law of averages if nothing else – it turns out to be not so bad as the worst case.
The other part is a sense of control. Worrying happens while there is no action, one just sits in a corner and dreads an upcoming trip to the dentist for example. And you worry and worry but the problem does not shrink – not even an inch.
So you end up spending nervous energy while the problem stays, you’re loosing.
But as soon as you are actually in the situation that was worrying you, often a sense of control takes over. Now you are experiencing what you feared, but at the same time, now that you are finally face to face with it, you can also start to do something about it. If nothing else you can survive it, and that alone is a victory in some cases.
So now you are exerting real energy, but the problem starts to recede, or move towards some kind of logical conclusion – now you’re winning.
Which is a long roundabout way of saying that action generates its own positive energy, and gives you the power to deal with things. Inaction, on the other hand simply leaves you feeling powerless.
As was said by Kipling:
The cure for this ill, is not to sit still
Or to frowst with a book by the fire.
But to take a large hoe – and a shovel also
And dig till you gently perspire
