Ask How do you keep track of multiple client deadlines without missing any of them?

[Edward22]

When you are working with more than one client at the same time, keeping up with deadlines can get messy very fast. One missed delivery can affect your reputation badly, especially when you are still building your name. Some freelancers use tools, some use simple calendars, and others just rely on habits they have developed over time. There are different ways people stay organized, and what works for one person might not work for another. How do you personally manage this without losing track?
