“A goal is a specific objective that you either achieve or don't sometime in the future. A system is something you do on a regular basis that increases your odds of happiness in the long run. If you do something every day, its a system. If you're waiting to achieve it someday in the future, it's a goal. If you achieve your goal, you celebrate and feel terrific, but only until you realize you just lost the thing that gave you purpose and direction. Your options are to feel empty and useless, perhaps enjoying the spoils of your success until they bore you, or set new goals and reenter the cycle of permanent presuccess failure. All I'm suggesting is that thinking of goals and systems as very different concepts has power. Goal-oriented people exist in a state of continuous presuccess failure at best, and permanent failure at worst if things never work out. Systems people succeed every time they apply their systems, in the sense that they did what they intended to do. The goals people are fighting the feeling of discouragement at each turn. The systems people are feeling good everytime they apply their system. That's a big difference in terms of maintaining your personal energy in the right direction.”
