I most admire Mad Saints / Crazy Sages because it requires great courage to show a path of thwarting convention, and it demonstrates a level of freedom and self-realization unseen, elsewhere.

Furthermore, unlike the other major contenders, there is no bad motive for entering the field. So, if you want to talk on the whole. Many doctors chased pitiful motives like money, prestige, or simply doing what their parents told them to — unquestioningly. Some teachers became teachers based on the June through August dead time or the love of the power to make kids eat their meat by withholding the pudding. But all crazy sages became so because someone needs to point out the world outside the cave, and they had no capacity to do otherwise.
