Honestly?
It leaves me wondering how many young people you talk to on a regular basis.
I was the oldest person in my doctoral program, most of my classmates were early to mid 20s, and about to graduate as high earning medical professionals. These were intelligent, driven people who knew how to research and understand anything and everything important to them, and I had to explain the very basics of income tax to them.
I've worked professionally as someone who gives people career, business, and financial advice. My target audience has been people ranging from mid 20s to late 50s. I've learned through extensive experience that a list like yours would be confusing, intimidating, make very little sense, and would trigger them to feel stupid, and therefore to tune out your advice.
That's why MMM is so successful, he breaks down the most basic of basic concepts into digestible, easy to read and understand content, and even then, I usually have to prime someone with a bit of knowledge before referring them to the MMM website.
You talk about speaking to young people and then throw in concepts like "equity" and "growth potential" and "index funds". Any young person who understands those concepts is so ahead of the game that they already know where to look for high quality advice well beyond a bullet point list.
Personally, when I'm advising young people, I emphasize the following points
1: Most advice is terrible, even professional advice, it takes a lot of time and experience to learn to evaluate good information from bad, and many people don't bother. Start learning now, this isn't something that can reasonable wait, because it takes time. Getting a head start on truly understanding your own career and finances is what will make you rich and happy, not listening to advice, which is probably shitty.
2: Most people are unhealthy and unhappy, so general wisdom won't likely produce a very good life, if it's what everyone is doing, question HARD whether it's right for you, because the outcomes of what most people do are not great
3: Don't be the employee who benefits your employer best, be the employee who benefits your own life the best, you define what success looks like for yourself, if you and your employer can't come to an agreement on that success, then you aren't working for the right employer
4: Watch your indicators of wellness like a hawk: eating, sleeping, exercise, and relationships. If any of these things start lagging, something is very wrong with your life, and you need to act fast to resolve it. It will feel like the most normal thing in the world to let these factors start failing, because that's what everyone does, but remember #2, just because most people let themselves fall apart doesn't mean it's okay.
Note, I give very little specific, actionable advice, unless I have gotten to know the person as an individual, because you can't know what specific advice is needed for any given individual, and that's why most advice is SO TERRIBLE. That's why professional advice tends to be so terrible, it's not that all professionals are shitty advice givers, it's that their advice is by default shitty unless the person seeking it is able to be clear as to what they really need, and they can't be clear if they don't even know themselves, which is the case with most people.
So my advice for young, typically clueless people is to emphasize the importance of truly understanding these things for themselves, to not just follow paths that are set for them, and to question at all times anything and EVERYTHING that appears to be "common knowledge" or "normal".
It's very destabilizing and very upsetting for them because they so desperately want to perceive the world as full of proper adults who know what they are doing, who can tell them predictably how to follow the predictable path to success. But that path is a joke, most adults are a joke, and the sooner they grapple with the angst that comes with that realization, the quicker they can actually prepare themselves to be successful on their own terms.
