I vehemently disagree with your post. Minyan= consistency. Those people who daven early in the morning every single day are the ones that are sucessfull and responsible. They have a set schedule and and will not deviate from anything. My father has been davening at the same 6:30 minyan for the past twenty years and always underscores the importance of minyan.
However, the people who show up to an 11:00 minyan are those that don’t have a plan or set schedule. They are inconsistent. How will they show up at 9am every morning when/if they get a job? Those are the people whom I would not want to marry if I was a girl.
Sounds like you are a girl, since you refer to your father instead of yourself. So, for purposes of this discussion, just imagine that minyan to you is like childbirth to men–you will never know what it is like and will have to rely on others to tell you.
I’m not talking about people who get up at 11. I’m talking about people who come on time to seder at 930, but don’t go to minyan at 730 on time every day. Rather, they come at 740, and occasionally at 750, and occasionally daven in the laundry room. Or, they always daven in the laundry room. Or, they go down the street to the other minyan which davens at 815. Or, whatever.
So, you’ll say you can just ask about if they come to seder on time. Unfortunately, there are very many people who don’t come to seder on time. Within 20 minutes is basically regarded as on time, in many places.
And the people I am talking about, are often the guys who if you asked me–and I decided to answer honestly–are the responsible guys in yeshiva. Often, the people who come on time every day are not the most responsible guys. I have not seen a very direct correlation between guys I consider responsible and guys who come on time to shachris.
And when they leave yeshiva, and need to get something done–they do it. Well.
