This is a tricky one in that it’s almost an exact split between helpful and misleading. The general thrust of it is valuable but it’s aim is off in that it presumes a person can change someone else and that simply isn’t true. But to the quote’s point, even we will only change ourselves when we see more value in going a new direction than in the old one. So remember: you don’t succeed in life by getting people to change their actions through coercion, manipulation or force because as soon as those forces lift things start to go back to their nature. This applies to parenting, dating and employing people. Real and ongoing change only happens because the person themselves sees and values the world around them differently. Because of that shift in perspective they will initiate change themselves—not as a way of stopping one activity, but as a way of starting a new one. And sometimes they need to suffer a lot more than you before they’ll choose a new path and even then they might not pick the one you were hoping for. So don’t blame people for living their lives. Just live yours and then align yourself with those in your natural tribe of behaviour. That is your real family and for as long as you are a part of it you won’t be asked to change. But remember: everyone and everything inevitably changes, so it’ll only be your family for about seven to nine years and then you’ll have to find a new one or your life will get static. And when you do that you won’t do it because you perceived something wrong about your current life, it’ll be because you see something promising off in a new direction. So to stay healthy throughout your life it’s really as easy as staying vigilant for promising things.
