The biggest impact you can have in the lives of others is through your own life. The more you improve yourself, the more you can improve the lives of others; both through your work and through your own example.
People will change when they want to change or when they’re forced to change. Allow people to be, and allow the universe to guide everyone at their own pace.
Whatever your goals are, you will always be most effective by focusing on what you do control—yourself and your direct environment.
And even if the world does go to pieces, allow it, for your power always starts with you.
