When you give someone instructions, check to be sure they’ve made a note of them. If not, you should be concerned.

The unlearned and uncommitted tend to trust their memory, but the shortest pencil is still better than the longest memory.

When someone doesn’t consider what you’re saying important enough to write down, they are sending you a signal; the light is flashing red. Those who are follow-through people always ask additional questions about the assignment and instructions you give them.

When someone tells you, ‘I’ll try to get to it,’ that’s another flashing red light, because they probably won’t. The word try often reveals half-heartedness.

In other words: only give instructions to someone who is qualified to receive and implement them.

‘A man convinced against his will, is of the same opinion still.’
