Marketing question: 1 method, a few methods, or many methods?

Hi,

At one point I helped put on daytrading seminars, and talking to attendees often brought out the point that newbie traders tend to think it's better to know 10 systems than one system, using the logic that you'll get 10 times as many signals and make 10 times as much money. It turns out that that logic is flawed, and that a trader who masters one system tends to do better than traders who 'know' ten trading methods.

I wonder if this truism applies to product sellers? Is it 'better' to master and apply one marketing method, such as JVs, than it is to 'know' and try to use 10 marketing methods? What if one can master a few methods, and sets up an organization to systematically use these few? Would that be better still?

What do you think?

Thanks in advance for all replies ...

Best,
