If you're in a small or solo practice, after you've conquered a particular tech task, reward yourself in a way that satisfies you. When you do something well, brag about it. The technology is not easy. Using electronic filing, offering clients an electronic version of a newsletter, or joining a tech committee in the bar, are achievements that are as deserving of praise as any golf score, and frequently more meaningful. Always deliver more than promised.
Quizzes are useful ways to learn and to reinforce what is taught.
Lawyers are competitive animals who did well in school. Offer prizes and congratulate the winners. Get carried away. Human beings use only a small percentage of the 10 trillion brain cells we possess, and there's not much we can do about that today. But without tech training, we use only a small fraction of our software's capabilities.
