58 here. In my thirties, the first thing I did was blow off my research job and travel with my wife for a six-month trip around the world. If you are not sure that you married the right person, traveling will be a good test! Of course, I had no money after that trip -- so we lived with my in-laws for six months to save for a house down payment. I would not recommend this! But what I would recommend is living under your income in your thirties. It would be best if you did that forever, BTW. And have kids. They take a lot of energy, time, and love. Finally, invest in your career. Take new roles, try some things. Don't sweat not being the next Zuckerberg. You have three or four more decades to start a company, write your novel, or create the wondrous thing. Load your backpack full of responsibilities in your thirties -- you are stronger than you think.
