Not much can change on the global scale, or even in my community (or even in my house), if I’m not thoughtful and intentional about my own personal behavior. I know that. You probably know that, too.
But I’d also say, not much can change if I’m not thoughtful and intentional in a specific way: by being a little (or a lot) more generous; by committing, and making sure, that nothing I say or do will cause harm; and by taking the time, no matter how busy I am, and no matter how much the world throws at me, to train my heart and mind to be still.
