the goal isn't to become some emotionless monk who never feels anger, envy, lust or greed. those impulses are going to show up whether you like it or not.
the skill is deciding what happens next.
envy can become information about what you actually want. anger can become fuel for training or solving a problem. ambition can push you to build something instead of settling. even lust can be redirected into improving your social life and actually pursuing real connection.
but there's a line between using an emotion and letting it use you. the moment your “fuel” starts making your decisions for you, you're back to being controlled.
master the impulse, don't pretend you don't have one.
The easier version of self-control is resisting temptation. The harder version is learning controlled restraint. Wrath, Envy, Greed, Lust, Gluttony, Pride and Sloth, rather than controlling the expression of your temptation. You master them. You channelize and deploy them in a controlled manner. Greed for long-term actualisation of your purpose. Envy to motivate you. Wrath to out-compete others. This is how you use your demons to do your bidding.
