If you are planning to sell a home and are interviewing listing agents, ask if they have any near-term vacation plans - and then ask about back-up support in their absence. Everyone is entitled to time off, but you want to make sure your home sale doesn't have to take a vacation when your agent does.
If you plan to refurbish a major shop tool or other equipment, take some photos before you start. They possibly can save you some head-scratching during the reassembly process. Take pictures from a number of angles, and take close-ups of areas where you think you might have some questions later. The more complex the machine, the more photos you should take.
