As a teenager, I was enthralled with Katniss's bravery, archery skills, and all-around badassery. But as an adult, I see how her keen resourcefulness is the result of complete incompetence from the adults in her life. Katniss's mother is a skilled nurse but doesn't offer much in the way of parenting advice or personality in general. Haymitch brings a certain kind of swaggering charm, but he's also a barely functioning alcoholic whose best piece of advice is "don't die," while Effie Trinket is more concerned with good hair and manners than the morality of the games.
The adults in power are no better. President Coin spends the first half of the Mockingjay installment livid that she can't control the Mockingjay and the second half trying to get her killed to further the resistance. Honestly, with adults like these in charge, it's no wonder a teenager leads the resistance.
