Early in my career, I said yes to everything. Carousel? Sure. Three more CTAs? I'll make it work. Extra section above the fold? On it. I thought being good at design meant making any request look presentable.
It took me a while to realize that the most impactful thing a designer can do is push back. Not to be difficult, but because every element you add competes with every other element. More stuff doesn't mean more value. It usually means more noise. The products I'm proudest of are defined by what we took out.
This is even more relevant now that AI can generate anything instantly. The temptation is to add more because it's easy. But easy doesn't mean right. Restraint is harder when creation is cheap. And that makes it more important, not less.
