It is important to help people let them imagine themselves living in your house.
Many experts recommend removing or storing items that have a lot of personal information.
It should still be livable but remember you will have to box this stuff anyways, why not get it out of the way and make the house look bigger. Remember not everyone drinks, smokes, is your religion, or participates in your hobbies. I wouldn't hide anything but may want to limit some things that are taking up counter space. That beer bottle collection of the world - might be a good time to box that up. Weekends house should look best.
