None of us is fixed, each of us changes, in one way or another, either willingly, or against his will. The crises you go through in your life cannot pass like this without leaving scars in yourself.
After human crises, travel and reading are the most changeable factors for anyone. The problem is that the changes to any of us are much faster than what was happening to the sons of Adam more than a decade ago. We are crazy, not one of us does not know what he wants, sometimes sharp-tempered at times.
