When there is pain, the animal instinct is 'fight or flight' (i.e., to either strike back or run away) - reflect instead. When you can calm yourself down, thinking about the dilemma that is causing you pain will bring you to a higher level and enlighten you, leading to progress.

I eat not because I want to, not because I have to overcome anything, not to prove myself to anyone, but because it's there. I eat because that's what people do.

Because one has the animal instinct to seek out the people that suits one - you see people that go on life's journeys and get muddled along the way. If you look at their lives they've always gone with the wrong people... can you say it's the wrong people - I don't know...

Yet there are those who insist the opposite: that we are creatures of instinct, like wolves.
