Design a YouTube thumbnail for a video about the book 'Rich Dad, Poor Dad', focusing on financial lessons. The thumbnail should show two contrasting images of father figures—one representing traditional views on money (serious, formal), and the other symbolizing wealth-building strategies (relaxed, confident). Use a split-screen style to emphasize the contrast. Include bold, minimal text that says: '¿Padre Rico o Padre Pobre?' in large, clear font. The background should include elements related to finance like cash, coins, or graphs, without overwhelming the viewer. The tone should be motivational, engaging, and educational.
