I definitely try to take my time, I've learned the hard way that rushing or losing concentration leads to guitar shaped firewood
I try to keep my work as neat as possible, although not because it makes a good photo, there's always a practical reason why I do something.. for example, I square off the edges of the headstock after the veneers have been glued on, as it means I can place my set square against the edge when marking out the centre line, etc and know that it's parallel.
