just thought id give you my take on it.
when its freezing and frosty like today i start around 10am and finish at 3-330pm.i dont earn as much but i tick over at a steady pace!still eating into my workload.
2 flasks.one with hot tea and one with hot water(in case jets freeze).gloves with disposable liners.goretex boots,jacket and fleece.
i find by not putting too much pressure on myself to get through my work im actually more productive!avoiding burnout and generally very little stress.
leaving an oil filled radiator in back of van so its nice and toasty in the morning also helps!
is that the time?better get off to work!!
any other tips from you other guys?

best wishes to you all
regards
