You make a good point, and Rollo puts the research out there that you become extremely attractive as a man in his 30's+ to younger women, as you've established yourself in life. Why not take advantage of the power-up you've gotten?

Reddit finds large age gaps predatory. It's only "sex positive" when its a woman and her students.

Off the cuff, things to look out for I can think of.

Jokes about "generation gaps" are mild shit tests. DARE, non DEER.

If you are are serious about starting a family one day, not necessarily with her but your mission includes it, weigh the pros and cons to start term life insurance now if you haven't already. It gets expensive in a hurry from here on out for you when you think in terms of enough for a year or two for your family. Lock in the low premiums and good terms now, or look up what it costs later and plan to pay those premiums.

Take care of your health. Be in at least the top 5-10% of men in your age cohort, if not better. Do not give her any feeling that she might have made a mistake choosing a much older man.

Set spending habits now. Unless she's very unusually raised, she will be too young to have absorbed frugality and high time preference lessons. Do not, under any circumstances, reveal details of your financial life. That knowledge is distortive at this phase of your relationship, and she's too young to know how to properly use it in any case. Lead her by example, reveling in your tight-fisted Scottish frugality. Know the difference between tightness and cheapness. Know the difference between value and price.

Number one stress on LTR/marriages of money is rooted in hypergamy, but women fall prey to sunk cost fallacy just like anyone, and will generally not actively seek a branch for financial reasons if you are constantly making progress measured over a running 3-5 years. Here, habits of not consuming ad-supported media, and avoiding any nexus of the madding crowd pays dividends. Watch her actions as always, non-judgementally observe her friend circles. The time to show judgement is when you either approvingly accept her friend circle, or end the relationship because of them. It takes an exceptionally rare girl who rejects the allure of the attention economy boosted by those she surrounds herself with at such a remove of age from you.

At any time, for any reason, or no reason at all, make sure by your actions you demonstrate to her that she's free to leave. Just your turn. Until it isn't, many years or ideally around a decade later. If you are many of her "firsts", then the idea of permanence in many different aspects will scare the shit out of her at this stage when push comes to shove. A light touch is needed here. Even if she goes into the "what are we" area (for me personally that is a deal breaker, but you do you), you are the leader here.

Maintain your mission. Glorify your Grind. It is okay to occasionally get intoxicated for a few days within the relationship itself, but never forget yourself.
