There's his problem right there. Limit yourself to "writing" and you are unemployed. Even then, he could try self-publising a book, teaching as an adjunct English prof (I know there are jobs teaching immigrants English), or something other than whinging screeds about how unfair life is. No one wants to read that stuff!
Oh, and last I heard UPS is hiring. Of course he may have to actually lift something other than a pencil.
Nice of you to be so compassionate. No where does the author say all his applications were for writing work, just that he does seek out work in a field in which he feels competent. Perhaps he has applied for jobs that don’t require a pencil.
