Advisers
Being an adviser can feel a bit weird sometimes. You can be so useful, and yet so useless, both at the same time.
Maybe you're a doctor trying to get your patient to exercise more, or maybe you're a IT consultant trying to get your client to adhere to security best practices. Whatever it is, your job is to help them help themselves.
Your advice is only helpful if acted upon, otherwise you might as well tell them a funny joke. At least it keeps them happy.
It would be so much easier if you could intervene directly. Knock on their door and drag them to the gym, or barge into their office and toughen their server infrastructure. But even if you could, it's not going to be sustainable.
You can lead a horse to water, but you can't make it drink. That's the role of advisers, perhaps it's not something to feel bad about.
