I've learned this applies to a lot of life. Being a good manager, tech lead, consultant, etc, advisor, parent, friend, etc, is sometimes just half being a good therapist and helping them regulate.

I've watched a lot of "not officially financial advice" finance videos on YouTube (the solid people, not grifters), and while the financial theory side is interesting, when they talk about pragmatic investing and patterns of client behavior they have dealt with professionally, a large part of it is emotion management. Convincing clients to stick with a solid plan even when this month is abnormally bad, or avoid going all-in on the latest hotness, etc.
