Forums IMPORTANT: PLEASE READ Genius Code Direct Learning - Selecting books

In the manual of GC (p.21) I read that for DL "it can be helpful to choose books that are metaphors for the behaviors your studying"

Now, the example given is gardening or sailing. My question is: do you already have to be good in solving problems at gardening or sailing, so this will serve as a model?

Or is it that the skill (e.g. problem solving) one would like to improve/acquire will be used in the context of 'the metaphor of life' (here gardening or sailing) book?

Regards,
P.
