Who wouldn't "accept" new clients.... you then have the choice to reject them if they don't fit the pie before signing them on.
I know a guy who has 600 million under management and he "accepts" new clients. Thats how he got there.
Good advice. I also think that your disipline to not trade those times in which you lose is also superior to many others trading aptitude. I think one of the hardest things to do is resisting pulling the trigger on a whim for a new trade.
