Sun Tzu said: 5. If you are anxious to fight, you should not go to meet the invader near a river which he has to cross. 6. Moor your craft higher up than the enemy, and facing the sun. Do not move up-stream to meet the enemy. So much for river warfare.
In business: 5. If you are anxious to fight, you should not fight the competitor at a time when he has to win a particular deal. 6. Moor your craft with your profitable segments. Do not move against the competition in an unprofitable market. So much for capturing profitable business.
