Your mind set changes bexause you see it as income because you're not cleaning it like I said employing it becomes a numbers game,I sub out work I wouldn't do myself that's the proof it was good I'd have it for myself. You need to have had hard graft before to know what's an easy day cleaning Windows,I've done the 20 + houses a day jobs that is not an easy day cleaning Windows,doing 6-7 jobs a day is it's full time money for part time hours if you so wish but if your greedy like me and can get it down to even less jobs than that it's happy days,people that are doing 25-30 jobs a week know I'm right.
