@I'm not paid to think: I don't think it's contradictory, but it definitely is a bit confusing. I'd like to go into more detail but I'm worried I'd start rambling. But for example: one month I may become upset about being unable to write a particular program in an efficient way, or another month I might become frustrated getting to grips with some new framework, or another month it might be some other task that's totally different. In each case something definite causes the anxiety, but the collection of all those things don't appear to have much in common.
