My motivation is not financial but rather adding something historic and positive to the world. My time on this earth is limited. A company can outlive it's founders. I could care less about status or wealth, I got a good degree and will probably find a stable job in a law office in a few years - for what? I enjoy the thrill of taking chances and learning from mistakes. What is a full bank account worth if you won't use it? Some people my age buy cars etc but again - that seems very bland.
I live by the motto of collecting things that can't be taken away from me - that is what I have in my brain. Take all the wealth away from Elon or Jeff Bezos and they'd be billionaires in no time again. How? Experience.
100x6 months = 50 years and then you die. Life is short. Why should I spend the little time I have working on another mans dream? We have a danish saying that "Things comes together in a higher unity" aka life is like a huge puzzle game.
TLDR: Don't be a career. Life is not evolution. You don’t go step 1 -> 2 -> 3 and so on. You can go from step 3-> step 67.
Ask the girl. Shoot the shot. Launch the business. Run the ad. Quit the job. Take the risk.
