Well, personally I think the smoking thread is relevant because if you're fitter, your body and mind are more efficient; therefore you work smarter and do more, therefore earning more money.
Taking care of your body is just as important as taking care of your 'hands', and taking care of your hands is a subject that will be covered in the next issue of PWC. So, if for example, you've got lung cancer, you may find it difficult climbing ladders; no matter how good your hands are.
However, in my experience, 'love' or being in 'love' distracts you from work and another by-product is that it leaves you knackered; if you know what I mean
. So it's the complete opposite of not smoking! So you become less focussed and efficient.
So, Graham, who often makes me laugh and I've got nothing against him (literally or metaphorically), was, well being Graham when he started that thread.
Therefore, unless you can better explain how and why being in love with a customer helps you to run a window cleaning business; then it'll remain locked.
