I've no idea, because that's not how effective people behave. I say again: versatility does not mean building up a large portfolio of options in the erronious belief that "he with the most options wins".

First, it's not an erroneous belief - it's true much more often than it's not true. My experiences and experiences of many people I know will justify that.

Versatility means being able to do many different things - it has prerequisites (planning and creating options) and it also has benefits (leads to more opportunities). Connect the dots...
