This concept of dedicating oneself to becoming an expert in a particular area is a powerful message that can be applied to various aspects of life, including personal development, career advancement, and academic pursuits.

When Haggai speaks of "gathering in your resources," he is referring to the idea of taking stock of all the assets and tools at one's disposal. This can include not only tangible resources such as financial capital, equipment, and materials, but also intangible resources such as knowledge, skills, and personal connections. By gathering these resources, individuals can better understand what they have available to them and how they can leverage these assets to achieve their goals.

The call to "rally all your faculties" urges individuals to bring together all of their mental and physical abilities in pursuit of mastery.

Rather than spreading oneself thin across multiple areas, Haggai advocates for a deep and singular focus on a specific field. By concentrating all of one's capacities on this pursuit, individuals can achieve a level of expertise and proficiency that may not be attainable through a more scattered approach.

This quote aligns with the concept of deliberate practice, popularized by psychologist Anders Ericsson, which emphasizes the importance of focused, purposeful, and intensive efforts to improve performance in a specific domain.
