Well put
"Either the people you work for and with will back you and value the service you provide or they are going to continue to make whatever you do worthless."
You put it into perspective nicely!
I've found myself in the latter situation too often, and wondered how come I got demotivated, stopped producing anything meaningful, and felt generally worthless despite normally being reasonably capable, productive enough to pass general muster, and capable to be cheerfully cynical.
I've always written it off to lack of inspiration in unimaginative environments, but the notion of value seems much more relevant.
