There is particular experiment which I would love to reiterate here.

Some scientists placed a northern pike in an aquarium that had a glass divider separating the pike from a dozen minnows on the other side of the partition. The pike couldn’t see the glass when he repeatedly charged the minnows. Time and again, the pike went for a meal of minnows. Each time he slammed into the invisible barrier. Finally, after many days of failure, the pike quit trying. Then the experimenters removed the glass divider that the protected the minnows from being eaten.

Guess what? The pike didn’t try to devour the minnows even when they got right up to his nose. Eventually it starved to death with food swimming all around it.

Conditioning...

Realize that circumstances change, people change, situations change. It is very important to have belief in oneself, appreciation for oneself. Evry person, situation and circumstance has a better nature of its or their own. Life is the art of learning to find and appeal to these better natures; be it mine or others'.
