Test-Driven Development (TDD) gives you the peace of mind to sleep well, knowing your code is robust and reliable. By writing tests before the implementation, you ensure that each change meets the requirements and works as intended, reducing the anxiety of unexpected bugs. TDD also enhances the requirements stage, as it forces clear, precise specifications, leading to a more predictable and controlled development process.
