I’ve never met a guy who works full time who even does daf yomi daily. Best I’ve ever found is someone who occasionally does a daf. “
My son works full time and learns every night. My husband attends a daf yomi every night and around half the guys there are employed full time (other half, like my husband, are retired). There are many such Daf Yomi groups in my neighborhood, and several guys learn Daf Yomi every morning in one car of the train in which they commute to work every day. Where there is a will, there is always a way.
I think some people are afraid that once a bochur is no longer in the safe confines of the Yeshivah, under the watchful eye of his Mashgiach, he will Ch”V actually NOT make the time to learn regularly (because who will know if he does or doesn’t?). That is really sad, and even sadder were it to be true. Earning a living (and training to do so) is crucial to learning. Im ein kemach, ein Torah.
