Without the context the quote seems very egotistical. With the context I think it makes perfect sense. Your comment draws a completely different picture. I can’t juggle. I definitely can’t juggle multiple clients and serve them well on the thin time margins I’m keeping. I’ve always failed when I tried. I know my limits. I don’t want my reputation and talent to take me where my integrity can’t sustain me (and it will, if left unchecked). It damages my rep and renders my talent meaningless in the grand scheme of client services. “He’s real talented, but he doesn’t do what he says” is a massive failure unless my goal is to be known as an unprofessional, out of work, real talented guy. I’d rather serve one client to the best of my abilities than multiple clients simultaneously, mediocrely.
