I believe that -What was your school career, especially after the bac? is about bachelor degree (3-4 years of studying) -What are the possible evolutions of your profession whether you are self-employed or hired by a company? - I'd rather get a job by company just to study how to operate with people about work stuff. And then you could try to rbn out your business.
in student years my friend and I tried to do smth like that, it ended so quickly, from then I'm employed by companies, for today I am finance manager for rabato.com, in future maybe some years I'll run our my own business
