shaun.the best bit of advice ever given to me was(and given to me by a top class reality based pro )have 400 times the amount you want to win weekly.i.e if you want to win 1000 a week have a bank of 400000.are you incredulous yet.consider.
every fulltime proffessional even people like the late don scott (and he was the best in the business)go through horrendous runs of outs many times(a run of 30 is not uncommon).it is mathematically impossible not to.
always cover yourself for the worst case scenario.it will give you piece of mind if nothing else.
