Psychology, unlike chemistry, unlike algebra, unlike literature, is an owner's manual for your own mind. It's a guide to life. What could be more important than grounding young people in the scientific information that they need to live happy, healthy, productive lives? To have good relationships?
If you set goals for yourself, and you're like a lot of other people, you probably realize it's not that your goals are physically impossible that's keeping you from achieving them; it's that you lack the self-discipline to stick to them. It's physically possible to lose weight. It's physically possible to exercise more.
I think self-discipline is something, it's like a muscle. The more you exercise it, the stronger it gets.
One of the primary reasons why the human brain has evolved to look so far into the future is so that we can take actions in the present that will bring us to a better future rather than a worse one.
Let's face it: the present self is present. It's in control. It's in power right now. It has these strong, heroic arms that can lift doughnuts into your mouth. And the future self is not even around. It's off in the future. It's weak. It doesn't even have a lawyer present.
