No. 2: learn something. Your brain is capable of so much. Feed it. Learn something new. The greatest threat to progress is the belief that something is too complex to fix. Poverty is permanent. Racism will always exist. The Israeli-Palestinian conflict is too difficult to understand. The public education system is broken. Educate yourself, so you can be part of the conversation. Learn something scientific, something mathematic. Explore philosophy. Study paleontology. Try to learn a new language. You don’t even have to make fluency your goal, just get a few more words in your head. Listen to an educational podcast. Professors from colleges — such as Harvard, Yale, Columbia, Stanford — are offering their lectures online for free. Think of what you could learn. One of my greatest challenges as a teacher was convincing students they were smart after someone had told them they were dumb.
