Design a minimalist yet captivating book cover for a self-help guide titled 'THE FEAR FILTER: Stop Overthinking, Start Living: A No-BS Guide to Quieting Your Mind.' The cover should feature a serene, light-colored background—such as soft blues or gentle yellows—to evoke feelings of calmness and optimism. Incorporate subtle, abstract imagery that suggests the concept of filtering or clearing the mind, creating a sense of mystery and inviting curiosity. The design should be clean and modern, with the title and subtitle prominently displayed in clear, bold typography. Avoid clutter and ensure the overall aesthetic is professional and approachable, aligning with best-selling self-help book covers.
