Not so much one particular tip,but the amount I've upped my game since the book match job in Hampstead. The time taken to plan and set that out resulted in a beaut of a job and I guess that job for me was sort of inspiration. I've always had the mantra of "plan your work and work to your plan", but I've never had to tackle a job with that much planing and technical detail. So for me I suppose it's gave me more confidence, don't get me wrong I've been involved and been responsible for some very large contracts like full airport refits and countless shopping centres, completly new housing estates and schools etc, but that's all relatively straightforward work if you can use a protractor, compass and calculator lol, but having watched that job unfold bit by bit I now relish the chance to tackle something like that.
So my tip would be watch and learn, everyday is a school day!
