JMH: The OP asked for a serious learner/earner, DY said that we are a minority.
Read the OP again. And read DY’s posts again too. The OP is looking for a learner/earner, and DY says that it barely exists. You are saying that learner/earners are serious. Apples and pizza.
I don’t know with who you are arguing with over here.
P.S. Most of the workers that also learn a little bit (that I am familiar with), aren’t too serious about their learning.
