I am currently working as a consultant and I like it. It also makes upset/happy/schadenfroh (not entirely sure how I feel about it) when we tell the client what work needs to be done in which order and why just so they can throw it all overboard and we do it the way they want it and it bites them in the ass a few month down the line.
They hire us for the external professional experience that we bring, so listen to us. We did this before, we know what works, and we know way your way does not work.
