Stable income: Somewhat stable

As a product mockup designer, based on online research and my knowledge, the income can be moderately stable. While there is demand for product mockup services, the income can fluctuate depending on clients and projects. Some months may be busier than others, leading to variability in earnings. Overall, it may provide a decent baseline income, but it may not be as predictable as a traditional job. I'd rate it a 3 out of 5 because while it can be stable, it lacks the consistent predictability of a very stable income source.
