YAGNI — you aren't gonna need it

Don't build the feature you imagine you'll need next month. You're not a prophet, and the imagined future is usually wrong anyway — different users, different constraints, different priorities.

Build what's needed, keep it simple, and let the future feature earn its place. When it does arrive, you'll build it better — because now you know how it's really used.you're not a prophet
