I come from a family of ordinary Jews. My Dad was a working guy and never asked for handouts.
[link] And so was all my family from as far back as there are any records. We were what you could call Goldilocks Jews--not too hot, and not too cold, but just right. We had great respect for Torah--the Oral and Written Law.
If I had decided to learn Talmud along with my regular studies in high school and university my parents would have been thrilled. But instead I decided to spend all my time on Talmud and not prepare for any career. I certainly was not planning on using the Torah as a means of making a living.
Why I bring this up is part of my reasoning at the time was I simply found my abilities to be limited in subjects that I was interested in. And there were other subjects that I was interested in but I thought they had little value.
So what I suggest today is in fact
to learn Talmud Torah but not to use them as a means to make money. And in spite of the excuses people make to use Torah for a livelihood I have found that it usually leads to the dark side.--but not always. Clearly there were great roshei yeshiva like Reb Shmuel Berenbaum-the Rosh yeshiva of the Mir Yeshiva in NY who was the genuine article--a real gaon. So to be a Rosh Yeshiva was apparently considered as a kosher thing just like in Europe there was a job to be a rav. That was not being paid to learn or teach but give advice and take care of religious matters in town or in the yeshiva.
And as for subjects where it is allowed to make a livelihood I recommend the path of learning of
"Say the words and go on." [From the Talmud 63. לעולם לגרס איניש אע''ג דמשכח ואע''ג דלא ידע מאי קאמר Forever one should say the words and go on even though he forgets and even though he does not know what he is saying.]
I think that if I had known of this simple advice when I was younger I might have in fact been able to balance between Talmud learning and the other subjects I was interested in.
And if I had known the Rambam' opinions about learning the seven wisdoms that might have made a difference in my career choices. The Rambam holds learning Talmud is just to prepare a person to be able to learn Physics and Metaphysics. And it is by the later two that a person comes to human perfection.
