In "The Trusted Advisor," David H. Maister emphasizes the importance of making specific commitments to clients regarding smaller tasks. This includes promises like completing an article, making a call, or writing a draft by a certain deadline. These small commitments are crucial in building trust and demonstrating reliability.

Maister argues that consistently delivering on these promises, without fanfare, reinforces a professional's credibility with clients. By successfully fulfilling even minor obligations, advisors can foster stronger relationships and create a foundation of trust, which is essential for long-term success in client interactions.
