Not necessary to me. The push is important - this is undoubtedly, but what will push and how much, and besides, how much a person will push - it all varies. Circumstances can push them (for example, the death of loved ones or some kind of dissatisfaction with life), or people can (a good teacher, a friend who offends or, on the contrary, is too often offended). But how much and what a person will push depends on his character: you are inclined to go into dreams, or adhere to the principle of reality.

I am afraid that the question requires clarification, since it is unclear from what moment the process of cognition is considered to be launched. One of the options for the question. The child was born - it was not without a man - and then he was left in the forest. Suppose a she-wolf, as usual, could feed a baby. This baby is growing. What do we consider the condition for the beginning of the process of cognition in him? Rock painting or what?
If you start from my experience - you need it! All the processes of cognition for me started due to the fact that all my relatives are very smart people and know a lot. They answered my questions to the last.
They saw that I lacked knowledge and understanding in order to look for answers on my own. When I, in their opinion, grew to the age of thinking, they began to refer me to books, instead of citing them themselves.
