[Effects and side effects of the drug "Success"]

To raise the rate of success to 100% is certainly a goal worth striving for. However, the closer one approaches this ultimate success, the more one is confronted with unexpected difficulties, such as difficulties in recognizing and proving, extremely high success rates as well as ethical problems. Furthermore, in the range of a high success rate all attempts for further amelioration necessarily lead to deterioration of this success rate; this is illustrated by an example from ophthalmology. Actually, coping with success is a great challenge, and the teaching requires not only great skills but also a solid philosophical background. Teachers must meet high demands. This applies also to the general public and the authorities acting in its name who have to appoint gifted teachers and have to support their mission.
