I like those thoughts.  It's obvious, and something we take for granted, in the highly
flexibleand exploratory world of Smalltalk.  As soon as I read it I knew you were right.

I think people are "wired" or trained in different ways.  Some folks excel at
kinds of development while others really need that sense of safety they get from having
thought through things very carefully at the beginning.

I tend towards the "dive in and see if I really understand and what can I learn
But I think that comes from having learned that it is safe to do so because of the basic

smart things that have been learned so far that have kept me from drowning so far if I
make mistakes.  I realize that my approach may not be a good model for other to follow.
Too bad really.  I enjoy it this way.
