Research from Harvard Business School reveals consistent mindset differences between top earners and average performers:
1. ROI Thinking
High earners constantly calculate return on time invested. Before starting any task, they ask: "How does this contribute to my market value?"2. Strategic No
They say no to 80% of requests, focusing only on activities that align with their income goals. This isn't selfishness—it's strategy.3. Value Documentation
They meticulously track and communicate their contributions. If it's not documented and shared, it didn't happen.4. Market Awareness
They know their worth. High earners check salary benchmarks quarterly and understand exactly what skills command premium pay in their industry.
