Acting is rewarding, reacting is frustrating.
Every time you act on something, you are rewarded in some way. Not every conscious action will be successful. You may fail at times. Maybe many times. But you still get your reward. When you fail, the reward is in learning. You made a choice, you acted in a specific way and you learned something, even if the action was a complete failure.
If you react, all you get is frustration. You didn’t make a choice, you just responded to a stimulus. Maybe you wanted something else, but instead of choosing an action, you automatically reacted to that stimulus. There is no way you can get a reward if you’re reacting to something. Even if the initial stimulus was positive.
For instance, you blindly fall in love with somebody.That’s a positive stimulus and you reacted to it. After the initial, unconscious chemistry phase, you have a choice: to love and accept no matter what. If you don’t consciously chose to love no matter what, you’ll get hurt. Instead of accepting the other one, you’ll start to control him. In love, jealousy is a reaction, unconditional acceptance is a conscious action.
