Very helpful in this regard is doing test-first development. It takes a bit of time to get the hang of it, because it requires some imagination: you don’t normally think in terms of how a non-existent API would look like. The benefit is that it forces you to write code that *uses* an interface before you write the code that *implements* it; this way, it drives you toward designing your interfaces from the perspective of a user rather than from the perspective of the implementer. As a result, they’ll tend to be much more usable, regardless of how deeply you understand what makes an interface better and how much of a conscious effort you make to apply your understanding.
