Thank you for playing and congratulations for winning.
To explain the gain - protect scale.
Each interaction has the protect/gain properties. For example repair or food preservation helps her to protect what she has. On the other hand hunting helps her to gain new resources. There are conditions like "I can't secure her enough." Which implies that it will be better in that scenario to focus on the gain type of skills and knowledge.
But you can always win with any strategy. Going against the scenario will only make it harder. :)
