Can you place an 11-year-old in Jail for abusing a 4-year-old? This includes the 11-year-old shutting the 4-year-old in closets, hitting the 4-year-old, pulling the four-year-olds arms like they're nothing, yelling at the four-year-old for trying to cuddle, etc. would a small video of the 11-year-old yelling at the 4-year-old and pulling the four-year-old's arm suffice as proof? just curious.

There are two ways to view intelligence or ability:
ability it is fixed or ingrained – in other words, we are born with a certain level of ability and we cannot change that. this is called a fixed mindset.
we can develop our ability through hard work and effort. this is called a growth mindset.
these two different beliefs lead to different behaviour, and also to different results. for example, students with a growth mindset were shown to increase their grades over time. those who believed that their intelligence was ingrained did not; in fact, their grades got worse.
having a growth mindset (the belief that you are in control of your own ability, and can learn and improve) is the key to success.
yes, hard work, effort, and persistence are all important, but not as important as having that underlying belief that you are in control of your own destiny.
