I do totally get this, because I got my degree in journalism (“I want to WRITE!!!”), then I graduated and found out that journalists make no money. So I got into tech support, then more into network/systems engineering stuff, got an MCSE, etc… Then a company hired me as a systems engineer, looked at my resume, and said, “Journalism? You can write???” Um, yeah. So now I’m a tech writer. And what’s weird is that I love it. I don’t think I was ever all that great as a network engineer. This is so much more up my alley.
I’m not sure how you can mix the coding side of you with the nutrition/health side, but I never thought my writing and IT thing would mix either. So I think you’ll figure out how to blend those worlds at some point, I’m guessing.
