Everyone wants a Learning Type Boy. Hopefully. The world cannot turn without them. Every boy should be as successful as he potentially can while in the confined walls of his Yeshiva or office. His goals should be aimed towards the great minds in Torah. It is the only way.
By acquiring (Torah’s vocabulary) a wife one must realize the burden of earning a parnosa. Whether one fills those responsibilities through Torah Umnoso, 7 yrs in medical school or even soliciting he must realize that it is his achrai’is.
In most cases a new couple is able to financially survive the 1st few yrs without a formal breadwinner. B”H to the current respectable generation that financially aids Torah. Why a person would run run run to make more more more money is fuelled by lack of success in the Yeshiva World. Take it slow, learn as much as you can while you can. There is no reason to rush into building your goyishe mindset of a family.
