Amazing answer, that last paragraph about feeling bad about yourself is exactly how I've felt. I've been working in agencies where you've been producing other peoples ideas and dreams but haven't been working towards anything I truly care about or believe in.

When I worked in-house, I was massively productive, agencies I've just fizzled out and now feel that boredom and malaise. I've been offered an amazing in-house opportunity that I've been ignoring for a while now, I think this has spurred me to a decision. Thanks again!
