You are a talented person (presumably a guy) and it is not surprising that you look for new opportunities to progress with what you have already achieved and to explore new potentialities (if that is a word). Perhaps you could brand your blog and create in that brand other people writing about other interesting professions. We spend so much time at work (well, I don't) and our employment is such an important influence on our perspectives on the world in which we occupy space and also our internal sense of identity, including cause and resolution of internal conflicts such as status anxiety and financial insecurity. I am not pretending to know anything very much about it but I am sure someone of your ability could explore themes such as this in your own profession and others, brand it and create a package for display through writing, radio, drama, it could be any media. Don't stop your blog though, it is good to read. Henry
