Answer:
The job, where things are predictable, has some important benefits. It creates an environment that provide for a lower amount of stress.
If you, in general, know what is going to happen, like with an accounting job, you can be prepared for it. With readiness comes less stress. This creates a nice comfort zone, which is a great advantage for some people. Meanwhile, if a job involves regular stressful events, as event organizing, which is still predictable, stress is inevitable.
In addition, a predictable work environment provides a good opportunity to plan and conduct long term projects smoothly. If you can rely on the predictions you can plan accordingly.
