I really am trying to be nice here but, you don't seemed to have grasped that the internet is just like Coronation street. None of it is actually real, with exception of a few people on here chances are you will probably never meet anyone in person.. Chillax dude !
due to where I live ( and me not being interested in travelling more than 30miles for graft) the vast majority of my plastering work is skimming who gives a fook, I have only screened one floor this year and that was only 9m2, if I'm lucky i may have rendered 200m2 , I have probably only done about the same of what I would class as proper float and set possibly less ( cos most Plasterer s talk about float and set like fishermen talk about the one that got away), again who gives a one.
Just take it all on the chin and move forward.
