Too Far: capricious
Saying: Carpe diem (Latin): “Seize the day.”
Observation: Automatic versus Spontaneous
Your automatic reactions are put into play immediately without thought. They could be very complex responses or as simple as flight or fight. Your habitual reactions have been created genetically over many generations. You can and have modified them somewhat by your conscious actions.
A spontaneous response could, at the least, be the same as an automatic response. But it also could be much more flexible. As you add a wider range of possible options, you extend your responsiveness.
