a. Those who do.
b. Those who don't.
c. And then there are those who want to (but still don't).
Reading aloud is a form of personal dedication that requires daily sacrifices, strong effort, will power and investment.
Yes, it is not for the feeble-hearted.
Once you commit, there is no way back.
It will knock out a sizeable chunk of your free time every day, leaving much less time for your other personal priorities and forcing you to reschedule some other events.
It is a job without any immediate reward and the possible rewards are down the line, many years down the line. (If they even materialize).
Reading aloud is also not a simple matter, as you need to prepare for your read aloud sessions by previewing every single book that you want to read beforehand.
That means looking at the book from start to finish - and the middle parts too!
That preparation phase can take up twice or three times as long as the reading itself.
