Sunday morning is different from the other days of a grand prix weekend because it is much more relaxed - the mood changes. On Saturday morning in particular, the build-up to qualifying is quite intense because of the nature of the session. Both Nico and Daniel Ricciardo have to perform at a high level for a short amount of time in qualifying, and you can't really approach a long race distance in the same way. Now most races start at 3.10pm local time, that makes Sundays quite drawn out.
Whatever happens on Saturday, it's important to draw a line under the result of qualifying. We know where we are starting and you can't change that, so it's important to focus on what is possible from that grid position.
I've worked with Nico for three years now and he quite likes to get up and get going. Drivers will often start by doing some warm-ups and activation at the hotel on Sunday morning.
