The rules are basic. They work. Yet we forget them all the time, or think that the latest fad will negate them. However, this is proved wrong with every wrong turn.

So:

• Simple is not the same as easy.
• Change takes time.
• Planning and preparation are vital.
• Monitoring the effect of your inputs is required.
• Getting the 80% right repeatedly gets you ahead of the rest of most of the competition.

If necessary, write these down and stick them on your wall.
