If you aren't destroying your enemies, it's because you have been conquered and assimilated, you do not even have an idea of who your enemies are. You have been brainwashed into believing you are your own enemy, and you are set against yourself. The enemy is laughing at you as you tear yourself to pieces. That is the most effective warfare an enemy can launch on his foes: confounding them.
Beware of people who tell you it can't be done. They want to remain on the market alone
The reason you don't succeed in life is because you are too lenient with your deadly enemies. Identify them and eradicate them completely, don't let any of their seed escape your vengeful sword. Don't negotiate with the enemy and never make deals with them. Only after you have wiped them out of the map will success smile at you
A bee, though small, can still sting you; an elephant, though calm, can still trample you; a lion, though full, can still devour you.
