Quote - A limited toolset is ideal IF those tools suit your way of working, 

And that's the thing, if you learn to model using a limited toolset then that toolset will, by definition, suit your way of working, so it's natural to become set in your ways.

It's only when you see a new tool in action (like through watching all the Hex training vids) that you think "wow! This tool would have made the so-and-so model so much easier!" But too much looking around can be bad too, you start to covet features in half a dozen different applications and grumble every time you have to do it in modeller X knowing it would be so much easier in modeller Y.
