Time is the most precious of all commodities. Of all things in the universe, only time is the one thing that no matter where we look, once lost, can never be found. Ironically, time is the one thing we squander the easiest.
Keep Your Word
When you say you will do something, you must do it. If you meet someone on the street and you say you will call to have lunch, then you must call. Very simple, just keep your word.
Stick To The Point
In all conversations, keep things directly to the point, say the minimum possible and do not go on long, off-track stories and explanations.
