A week into the new agency job, I’m having a great time doing creative things like concepting and brainstorming, but there’s still an afternoon slump where the ideas slow down. Even after all this time, I still have doubts that they’ll come back again the next morning, but I try not to worry and I think about this advice from Hem in A Moveable Feast: 

I learned not to think about anything that I was writing from the time I stopped writing until I started again the next day. That way my subconscious would be working on it and at the same time I would be listening to other people and noticing everything, I hoped; learning, I hoped; and I would read so that I would not think about my work and make myself impotent to it.
