I think I've been going about this all wrong.
But now I know better. Now I know not to dig in when the tools obviously aren't doing the job. Now I know that instead of shifting to second gear to plow up an enormous grade, it's often better to roll to the bottom of the mountain and take a different road, one where you can enjoy the scenery instead of feeling bad while other people pass you.
This is the next book I want to read: http://manning.com/pearson/
