Prompt
Create a realistic portrait of John Doerr, a middle-aged American investor and author, sitting in a professional setting with a warm and confident smile. He is wearing a suit and tie, with a slight hint of a tech-industry-inspired background, such as a subtle circuit board pattern or a few tech-related artifacts. Capture his personality and experience as a prominent figure in Silicon Valley, having invested in companies like Google, Amazon, and Uber, and being a well-known advocate for OKRs (Objectives and Key Results). Incorporate a few subtle hints to his philanthropic efforts, such as a small environmental or educational-related item in the background. Style: a photorealistic oil painting or a high-quality digital portrait.
