My experience with self-managed artists is quite negative - but this is entertainment industry related. Just the fact that there is somebody you can call during the day and get a definitive answer on a request, and who makes sure the talent is showing up and delivering on the negotiated the deal, is securing them deals they otherwise would never get. This is most certainly not something that one would classify as "hard work" but it is super valuable when "talent" meets "corporate".
