I hear this so often but is there any evidence for it? I just don't think it's true. If it is true then these are skills that can be learned, there is nothing magic about managing time. Peoples lives would on the whole be infinitely better. I haven't worked in an office for 4 years and my life is better, my families life is better, my work is better, my home is better, my environmental impact is much lower.
