DiCaprio has a new 20yr old girlfriend - a lot of angry people call him creep and disgusting

Younger women tend to want fun and excitement above all else.

When they ask what you did on the weekend it's great to be able to say something interesting, and ideally unpredictable. If you watched Netflix and bought groceries you're losing interest, but if you went windsurfing or attended a salsa class you're scoring points.

In general they're not looking to settle down that young so besides sexual attraction they are primarily seeking social proof. Someone exciting and charismatic. Younger women are more interested in cool experiences now than a secure future with a good husband later, so you need to bring that excitement to the table first and foremost. You would do better as a lower middle class badass than as a boring but wealthy dentist or accountant, because girls don't care much for fiscal stability until they're looking for beta bux.

Presenting yourself as interesting and different from the norm is useful, it gives them something they can talk or brag about among friends. Women obtain status vicariously through the men they're with, so if they date an interesting man they believe this makes them interesting by default. This is why you see broke scrawny musicians with hot girlfriends, because they lead an interesting life and have wide social circles.

Also, I've learned through experience that it's easy to accidentally talk your way out of a romantic encounter. A lot of college age girls think they've got it all figured out and are highly intolerant of opinions that don't match their own. Your goal isn't to educate or inform so all controversial subjects are a no-go; guide the conversation to positive topics. Think of it as pavlovian, you want your name and face associated with fun and excitement. Every time a friend asks about InsertNameHere you want their first thought to be positive and exciting, not serious and certainly not indifferent.

In short younger women are desperate to do cool things with cool people in cool places. If you want to build and maintain attraction it will help immensely if they think following you will lead to those things.
