I also think this is a good idea.
We are each individuals with little interaction with true "colleagues" in a work sense. Understanding why people choose to do what is important.
Without understanding, we merely copy others without solid critical analysis. There are many courses that can be taken. I would suggest the 'classics' and (to be consistent) do it your own way. Go through libraries, pick up what looks interesting and absorb it.
There are many course, but then you are again asking for somebody else to provide a thinking method for you. There are so many good books. Pick your own books, and then write your own.
That's my suggestion.
