everyone is different with different outgoings, i cant see how not beleiving others will get anyone anywhere...
there is a certin someone in swansea, who has a very good window cleaning business and from what i gather his outgoing are tiny as he plans everything to the tee, iv seen his vans and web ect and he really is on the ball my windy mates all say the same and his attitude is more or less as dirty windows said, , he knows so many people in the trade ie, vans sales window cleaning supplies and has so many customers his work load so high, he's beating his overheads by a mile, leaving hudge profits....iv seen some of his hosues he cleans , 35 and 45 pound a clean, he got the whole area,,,,,jealous much!! good luck to him
