Thanks for you comment Tantra. Does serotonin get activated by making plans and working towards them or does it hit when we achieve the goal? Or both? I’m not an expert in the science of it, but my belief is that that dopamine effect we receive when we make plans (i.e. build an image of ourselves in the future) comes from the anticipation we get from fulfilling that image, but once we achieve that goal it is not said that serotonin and dopamine will go up.
