The general approach of the Mir Yeshiva in NY when it came to life's questions was "learn Torah". [In pain English that means the oral and written Law: the Old Testament, the two Talmuds plus the midrashim.] That was at least the basic idea I got by hanging around the rosh yeshiva, Rav Shmuel Berenbaum. That is there was an implicit awareness that life has tons of difficulties and most of which simply have no "solution". That is just the way life is. As Jordan Peterson puts it: "Life is hard." [He means that it is implicitly hard, not because someone else is making it hard.]
So while there is no promises, still the idea was the only way to deal with life's difficulties is to learn Torah.
[There are differences in approach however. How much in depth learning and how much fast leaning and the proper balance seems to differ from Litvak yeshiva to any other Litvak yeshiva.]
The only two things I would like to add to this is the idea of Physics and Mathematics being part of the command to learn Torah as you can see in the last of the first four chapters of Mishna Torah where "Pardes" is defined as Physics and Metaphysics as the Greeks understood them, and then later where it is stated that one should divide the learning time into Tenach, Oral Law, and Gemara and in the category of Gemara is ''Pardes."
Plus the idea that even Math can be learned in that fast sort of way that is usually reserved for learning Gemara fast- that is to say the words and go on.
