First off, thanks for your hard work on the new model. It might not always seem it, but you are in a very enviable position: young, in your 20s, you have your entire career ahead of you.
12, 13 years ago I was the same as you, I just wanted everything right then and being financially secure seemed so far away. Now I'm 34, married, and have a pretty comfortable life in California. We own our home, we travel frequently and travel well, are thinking about a second condo in a city, and we get to drive the cars of our choice - currently a 2019 full-size L405 and a brand new Porsche Taycan, with an L460 coming to replace the L405. My spouse works in finance for a big firm, and I work in marketing for a film and television studio. We did this largely without parental support.
Even though we are comfortable, it's still a different type of struggle, more money, more bills, more taxes, more expectations to maintain a certain lifestyle. We call it golden handcuffs.
So, the first piece of advice I would give to anyone at any age in any industry: Pivot.
Don't get too comfortable with the status quo, instead get comfortable with the fact that technology, the economy and the world is constantly evolving, so always be ready to evolve your own skillset and mindset.
Secondly, be nice to absolutely every single person you ever encounter, no matter what a bellend they are (still have the Brit in me). It's amazing how small the world can be in your career.
Finally, thinking about your long term career, think about what you really really enjoy in life - whatever interests or hobbies that is - and then think about a way to monetize it. If you can find that secret sauce, you'll be a wealthy, but more important happy, fulfilled person.
