Two very similar BaZi, same TaYun but very different life. Who's the doctor?

Here, I have two very similar BaZi, with the only difference is in their year and day branches. Both have the same TaYun.
One of the BaZi belong to a fast learner, a successful doctor and the other belongs to a slow learner who have 强迫症 (OCD, Obsessive-compulsive disorder) started in his twenties which surprisingly getting better in his forties without much help.
