Changing People vs. Offering Advice/Help

On today’s coaching call I heard you saying that we should not try to change people and that if we experience negative emotions about them, we should coach ourselves.
What if there are people we care about that could use some of the tools we are using in SCS and we could offer them? Should we then keeping it to ourselves and let them find their tools in their own time?
Because then why would you offer advice to your children, for example?
