I always try and have:

An Energy Drink - For when I need something Done and there aren't many people to get it done
A Chamomile Drink - For when I get the full family, and I need to be able to keep peeps under control

I'll have these if lucky:

A New Fe/Male Outfit - I generally have these for when there's going to come a new generation, and I'll never know if I like what the new person has on
New Work Mags - I buy these whenever I can and use them as soon as possible. Sure, towards the end of the generation, they become less and less, so I use them frugally then, even saving a few to pass on to the next person that comes along
