"Create an eye-catching promotional image for an eBook titled 'Top 10 Productivity Hacks: Unlock Your Full Potential'. The image should feature a sleek, modern design with a digital theme. Include a stylized eBook cover with bold, clean typography and vibrant colors like blue and gold. The background should show a desk setup with a laptop, coffee cup, and a notebook, symbolizing productivity. Add subtle elements like glowing icons or light rays to give a tech-savvy, inspiring vibe. Ensure the title of the eBook is prominently displayed, with a tagline such as 'Boost Your Efficiency Today!' below it."
