We are all familiar with the sources of the problems that arise in the period of youth.
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 profession or career can take place smoothly.
But if he clings to illusions that are contrary to reality, then problems will surely arise.
No one can take the step into life without making certain assumptions, and occasionally these assumptions are false—that is, they do not fit the conditions into which one is thrown.
Often it is a question of exaggerated expectations, underestimation of difficulties, unjustified optimism, or a negative attitude.
One could compile quite a list of the false assumptions that give rise to the first conscious problems. ~Carl Jung, CW 8, Para 761
