gapingvoid writes about Unique Currency: basically it’s about the type of value proposition you’re building for yourself as an employee/freelance/business (your knowledge, skills etc) and the importance of it being unique.
This reminds me of a conversation I had with someone this week. He said he hated his job, but he’s doing it for the CV value. That is not always a good idea: your CV is a major way to determine your Unique Currency. Do you want to build your value to fit a type of work you don’t like?
