Psychological Warfare

After 4 years of searching of profitable system, now it's vrey hard ( i honestly admit it) for me to trust my profitable system! Have anybody else been facing such problem and how did you deal with it? maybe i'm to greedy?

Thank you in advance.

Risk the smallest possible percentage on every trade. If the system will prove himself to be a loser, your loss will be small. If it is profitable, you'll regain your confidence.
