Punishments erode relationships and moral growth.

Trying to do well and trying to beat others are two different things. Excellence and victory are conceptually distinct . . . and are experienced differently.

When we do things that are controlling, whether intentional or not, we are not going to get those long-term outcomes.

Educators remind us that what counts in a classroom is not what the teacher teaches; it’s what the learner learns.

To feel controlled is to lose interest.

There are different kinds of motivation, and the kind matters more than the amount.

Maximum difficulty isn't the same as optimal difficulty.
