A Crash Course In Self-Discipline Day!
Starting today, anytime you consider doing something to make yourself feel good, stick a thumbtack into your thigh instead. Like if you think, "I should eat a brownie or two," don't go out and buy yourself brownies. Stick a thumbtack into your thigh. Or if you think, "I've worked hard all week, I'm going to go fuck whores." Instead of going and fucking whores, stick a thunbtack into your thigh. Or if you decide, "That's it! I'm buying myself a Jeep!" Don't buy yourself a Jeep. Stick a thumbtack into your thigh.
After a few weeks of this, you won't want to do anything to make yourself feel good anymore.
Happy A Crash Course In Self-Discipline Day!
