Moving From a Big Company to Do a Startup Is Like Being a New Grad

A good analogy might be graduating from university and getting your first job. You might have been really really great at school, studying, getting good grades, whatever, but then realize it translates very poorly to that first job. So much was taken care of without you realizing it and very little prepares you for doing the job other than, well, doing the job.

Starting a company, especially after coming from a stint at a larger company, is a lot like that.
