Ask How do you handle last-minute urgent requests from clients without burning out?

[Brendan]

Some clients will wait until the last minute and then send a message saying they need a task finished in two hours. While I want to be helpful, I also know that rushing every time will make me feel very tired and frustrated. It is better to have a system where you charge more for rush jobs so that the extra stress is worth the effort. This encourages the client to plan better next time. How do you tell a client no when their request is just too sudden?
