i bet you wont earn £500 quid a week, my mates a tree surgeon and he was told he would earn so and so amount but they say you can earn 500 quid a week etc only if you work every fuking hour of the day, he goes to work at 6 and returns about 7 in the evening now thats a hard days graft climbing up trees with fuking heavy chainsaws etc

another thing to remember is you wont be young and agile forever, what about when your 45 and cant afford to retire and have terrible back etc just aint a longterm career imo

its a bit like labouring on a building site you can earn 500 quid a week cash if you can supply a few blokes all day with bricks cement etc but the fact is its bloody hard work and you wont be able to do it forever
