I Think So: A Transformative Self-Help Journey

a minimalist, modern e-book cover design for a self help book titled 'I Think So.' with a clean abstract face, head or profile as the central focus. Use soft, calming tones like sage green, light oranges and cream. Incorporate subtle organic shapes in the background for balance. The title should be in an elegant serif font, and the subtitle in clean sans-serif font. The overall design should feel empowering and calming, appealing to readers aged 25-40
