In a lot of offices, if you’re not typing or clicking – you’re not working. It’s an odd view for any member of an industry that prides itself on thought and creativity. To analyse a problem, understand it and come up with a creative solution to it, you need to think about it. Thinking, for most people, requires not doing.

So stop. Think. You’ll do better.

If you’re getting dirty looks from your boss, employ some body language. Frown, tap your pen on your lip or your thumb on the space bar, stare at your computer screen as if the answer is about to jump out of it. This is universal for “I’m thinking in the most useful manner possible” and is usually enough.

And if all else fails, just follow this time honoured tradition: go think in the toilet.
