I'll probably always be hired by someone else to build a shared vision and aspire to do it as well as I possibly can :)
I actually agree with the sentiment in your first comment. These aren't what defines if a company is successful. A good experience, care and craftsmanship are important, but not company defining.
I have decided for myself that most company defining areas are not where I want to gain expertise in (focused user research, finding PMF, funding, GTM, sales, marketing, etc) - I'm passionate about tech and am intentional about excellence in this area.
Which is why I will probably never establish a company. But of course I can lead a team to do good technical work and would like coworkers who do the same. One can dream ;)
