Don’t hesitate. You must create the
Bitul Torah? Bah. The whole Jewish world used to be farmers and merchants and artisans in Eretz Yisroel, for eg in the Tanach days. Was that bitual Torah? Nonsense. They worked the livelihood and learned when they could.
Even in preWW2 days, the laymen worked as labourers by day, and at night they came to the beis midrash and learned Ein Yaacov or Chayei Adam.
The Talmud even says learn with an occupation.
More importantly, a man without a proper job feels useless. No one will marry him, he himself feels like a loser.
Don’t even hesitate. You go to college or uni. You study and make something of yourself. You earn a proper a job. Make sure your yiddishkeit doesn’t get the backbench. And with your income you support people in need. The Free Loan Fund idea of the Chofetz Chaim, limud Torah, orphans…. Go study and learn!
