Here's the thing: You don't. You can't. There are no magic words to make someone see things your way. You can give them ideas to mull over, but you can't convince someone who doesn't want to be convinced. You can be open, express your views and give your reasons to anyone willing to listen, but that is the extent of what you can do. Some people may eventually come to you for advice; welcome them and guide them as you can. Most people may take some bits from you but never start actually caring. That's ok, that's their way.

You can't force people to do things your way, nor should you try. Just be honest.
