Phil, I totally agree with the learning through hours of struggle belief. There is a dark side to this drive however; when I work with others, or they have worked with me 🙂 it is not helpful to the "team" if instead of going on to your next assignment you spend those "hours" trying to figure out what went wrong. Yes, the answer might be important long term, but do not try to figure out why the house started on fire while the house is still burning.
