When the dream of childhood ends
/For most people it is the demands of life which harshly put an end to the dream of childhood. If the individual is sufficiently well prepared, the transition to a professional career may take place smoothly. But if he clings to illusions that contradict reality, then problems will surely arise. No one takes the step into life without making certain presuppositions—and occasionally they are false. That is, they may not fit the conditions into which one is thrown. It is often a question of exaggerated expectations, of under-estimation of difficulties, of unjustified optimism or of a negative attitude.
