The single most important decision in my career was to start developing open source software (OSS) and blogging about it. [..] I picked for them the most liberal license I could find (MIT) and companies from all over the world contacted me asking for customization and new features. My hourly rate was around $60 and I had to raise it on a daily basis because I couldn’t keep up with the increasing quote requests. Now I’m still a freelancer but I work for Microsoft and Google and my rate is at $150/h.
