Hi, it’s Hannah! Welcome to Nonlinear News, where I share advice for high achievers who refuse to choose between wealth and fulfillment.

Thank you for being here!


Getting a job 🤩 vs. starting a job 😔

i am so squidward unfortunately lol

You did it! You finally got the job you spent months (maybe even years) working towards - dozens of coffee chats, apps that disappeared into a black box, final round interviews that gave you false hope…now you’re onto the next phase of your career!!

But now you’re a few days before starting and thinking: I can’t do this…You start missing your old job where you knew how to do everything, who to ask for what, because it felt comfortable.


How I’d onboarded myself again

Three months ago, I left my comfortable remote job at a thousand-person tech company where I was one of five product marketers to join a 40-person startup where I’m the only marketer. I went from remote to in-office, structured to chaotic, and into an industry I’d never worked in before (fintech/crypto). Most 30-60-90 day plans didn’t feel like they fit.

Last month I posted a story on IG about how hard the first few months felt, and how it finally started clicking around month 3. I got dozens of DMs from people about to make similar moves: switching industries, taking pay cuts for long-term upside, joining smaller companies where they’ll be the first or only person in their role.

They all wanted to know: what do you actually do when there’s no structure and you’re expected to figure it out yourself?

Here’s how I’d do it again:

  1. Set these 3 goals before you start

  2. Expect the 3-month rollercoaster

  3. Build your 4-pillar onboarding plan: team, customers, product, industry

  4. Ask (the right) questions

  5. Know if you should quit
