It would be interesting to note what path the participants wanted to purse. Perhaps the yoga teacher wanted to start her own business, therefore, the career path she took was appropriate. I see the work in the movie studio relevant to achieving the role at the gaming company.
I find it entertaining at my organization, which is a government agency that is related to financial services that they want us to work on our “Career Development Plan”. At 46, I try to tell them that a Career Development Plan is not worth their time or mine. Perhaps it is beneficial for the 22 year old entry level employee and we can help them move around the organization, but like you said I don’t want to over plan.
