I voted 3, but was torn between 3 & 4.
This is because i know that my methods are pretty damn good, compared to any that i have seen. Yet they are still by no means perfect, sometimes fail, suffer periods of drawdown etc. and this is if i follow my rules correctly, maintain full concentration,don't make any mistakes and do not get screwed by the brokers, or suffer technical problems etc.
All in all, trading still feels pretty fragile. But so does going to an office every day, sharing the company of a bunch of sometimes frustrated, competitive, bitchy and unpleasant people.
