Postman I agree with you post abouts learning lessons, I learnt my many moons ago, I think you need to (well I do anyway) walk away from your trading job, like you would if you were employed.
For me I need the right home/work balance, to that end, I rent an office and work as professionally as I can, when I leave at night, I walk way with peace of mind.
When I'm home that's my family time, and to resist all temptation, I don't have internet access, I don't need it, kids have their iphones etc. and enables me to keep focus on what's important in life.
