ive noticed how the window cleaners that are agreeing with the OP are the ones that seem to be always moaning about the weather.miles behind with work and probably scratching a living together barely paying their bills!
i know what thats like.i too was just like that in attitude for years and my business suffered and a barely earned enough money to get by esp during spells of bad weather.
i also never had the balls to up my prices.i didnt have the confidence or the business acumen.
now i know im no "alan sugar"

........but its amazing what a change of attitude can do for you.
im harder in a business sense these days and im proud of my little business which is just going from strength to strength.
i dont lack confidence anymore as ive really upped my game over the last 5 years or so and provide a very reliable professional service.
ive never had it so good even with the bad weather of late.
very best wishes to you all
