I got money from all my different projects but never thought about them as companies, I used them to learn and pay for my hobbies. I never thought they could turn into real companies so I worked on them at night after my normal job.
Right now I got back to a project and idea I had back in 2008 when I even registered the domain and created the landing page and sketched a logo. Finally, I want to turn it into a real thing, into a company, but I still think about it as a project.
Same happens when I have to explain to family and friends why I left a well-paid job on tech in Ireland and moved back to my parents home in Spain to work on a website while the country is still broke. By saying "I'm working on a project" seems less serious. They still ask if I can live out of that but if I try to explain I'm working on a company people just freak out and things get really difficult to justify taking the attention out of what's important. Hope one day they understand.
