The most important change is not learning a specific tool — tools change quickly. The most important change is developing an AI-first mindset: the habit of asking, before starting any task, 'could AI do any part of this?' This question, asked consistently, builds a systematic scan for AI leverage in your work. It does not mean defaulting to AI for everything — some tasks are best done entirely by hand, some require human judgment that AI cannot replicate, and some are worth doing yourself for the learning they provide. But without the habit of asking the question, the default is always manual — and that default becomes increasingly inefficient as AI capabilities grow. The mindset shift is a question before a tool.
