How to Adult

At a sprawling university library, two students sit at adjacent carrels, studying for the same final exam. The first, a history major, is meticulously crafting flashcards, cross-referencing lecture notes with textbook chapters, her desk a fortress of organized highlighters and sticky notes. She feels the familiar, satisfying hum of diligent preparation. Next to her, a business major stares at the same textbook, but his mind is a whirlwind. His thoughts aren't on dates or treaties, but on the student loan statement that just arrived, the bewildering jargon of his first part-time job's W-4 form, and the nagging feeling that while he knows how to analyze a supply chain, he has no idea how to build a credit score. He feels a quiet, creeping panic that the most important tests are the ones for which no one provides a study guide.

That feeling of being academically prepared but practically adrift is precisely what Jake Cousineau encountered. As a high school history and economics teacher, he saw his brightest students, masters of complex academic subjects, graduate into a world of practicalities they were completely unequipped to handle. They could ace an exam on the Federal Reserve but didn't know how to open a high-yield savings account. They could write a brilliant essay but felt paralyzed by the thought of negotiating a salary. Frustrated by this gap, Cousineau began developing a 'financial adulting' class. The lessons were so popular and the need so evident that he expanded them into the clear, accessible guide that is "How to Adult," a direct answer to the questions his own students were asking.

Module 1: The Adulting Mindset

So, what does "adulting" even mean? The book defines it with a bit of humor. It’s a verb used by people who feel they're only part-time grown-ups. But behind the joke is a serious transition. It’s a shift from depending on others to taking ownership of your life. This is about a fundamental change in mindset.

The author suggests a key difference between adults and non-adults is emotional regulation. Real adults learn to control their emotions, not let emotions control them. When your computer crashes and you lose three hours of work, you breathe. You stay composed. You find a solution instead of spiraling into a tantrum. This emotional stability is a signal to yourself and others that you are reliable and can handle pressure.

From this foundation, we see that successful adults have a clear sense of direction. They develop goals beyond immediate gratification. It can be as simple as remembering to bring a reusable bag to the grocery store. Or making the conscious choice to go to bed at a decent hour on a "school night." A night before a workday. These small, deliberate actions build momentum. They are the tiny bricks that construct a responsible life.

Furthermore, this mindset requires a proactive stance. Adults are assertive and find solutions instead of avoiding problems. When faced with a challenge, the non-adult response is to ignore it, complain about it, or hope it goes away. The adult response is to confront it. You find a way to fix the leaky faucet. You have the difficult conversation with a coworker. You don't wait for permission or for someone else to solve your problems. You take the initiative. It’s about agency.

Finally, all these behaviors are part of a larger process. Cousineau frames it as a hierarchy of activities. You must "get your shit together" through small, consistent changes. No one wakes up one day and is a perfect adult. It starts with the basics. Get out of bed on time. Make your bed. Wear clean clothes. Eat something other than cereal for lunch. These small wins build self-respect and the capacity for bigger challenges. They prevent you from "losing your shit" when life inevitably gets complicated. It's a gradual ascent, not a sudden leap.

Module 2: The World of Work

Your career is more than just a job. It’s the engine of your financial independence. The book is blunt. Finding a job that you love and that pays well is like hitting the jackpot. For most people, work is something you endure during the week to fund your life on the weekend. The key is to navigate it effectively.

The first hurdle is the job interview. Here’s where the author’s advice gets tactical. Your job interview is a test of how adult you can appear. It’s a performance. When they ask for your greatest strength, the answer is not "I can eat seven hot dogs in under a minute." The answer is "I'm a hard-working team player and I love a challenge." When they ask for your weakness, the answer is not "I pick my nose." It’s "I'm a perfectionist and sometimes I work too hard." You are selling a stable, professional version of yourself.

Once you land the job, the next challenge is keeping it. This requires social intelligence. You retain your job by avoiding conflict and doing the work you're paid to do. It sounds simple, but it’s not. Don't call your boss a "knob," even if it’s true. Offer to make coffee for the team. It’s a small, selfless act that builds goodwill. It also gives you a moment away from your desk. Most importantly, do your assigned tasks. Procrastination and avoidance are career killers.

Now, let's turn to the daily grind. Many workplaces are filled with jargon. Learn to decode workplace "management speak," but avoid using it excessively. Terms like "blue sky thinking" or "let's touch base offline" are just complicated ways of saying simple things. "Blue sky thinking" means think about something. "Let's touch base offline" means I want to talk. Understanding them is useful. But using them too much can make you sound like you're trying too hard. Or worse, like you don't know what you're talking about. The book humorously notes that a sentence full of jargon often just means "I have no idea."

And here's the thing. The daily work can be draining. That's why it's so important to find a sustainable rhythm. You must maintain a work-life balance to avoid burnout. Too much work makes you a dull, exhausted person. Too much play, like spending all day on social media, means nothing gets done. The author describes a "Goldilocks zone." It’s that sweet spot where you are productive and financially stable, but also have time for rest, hobbies, and relationships. This balance is a constant adjustment.
