There is clearly some sort of obligation to walk in the ways of one's parents, [note 1] but it hard to know how far this goes-especially in cases where one's innate talents are not the same as one's parents. And Western society in definitely based on the idea of one finding his or her talents and going in that direction. Nor is there any concept in the West of doing both. Rather the way the West works in one person for one job. So how does one decide? I myself was in this sort of predicament, not having the same set of talents as my father. But I have tried somehow to walk the fine line between the areas where he excelled [STEM] and my own interests Gemara, and Tosphot.
So what comes out for me is more or less along the lines of Torah with Derech Eretz/work. A Balance between Physics and Math and the Avi Ezri of Rav Shach But I admire the great Litvak sages like the Gra, and Rav Shach who were able to devote all their time to Torah learning. Just that I never managed to succeed in that direction for reasons unknown tome.
[note 1] If you do not walk in the path of your parents, you are dishonoring them by definition.
