Regular and deliberate practice is an effective way to sharpen your creative and logical thinking skills. To do this, you can challenge yourself with puzzles, games, and riddles that require both creative and logical thinking. Additionally, reading books, articles, and blogs that expose you to different perspectives, opinions, and arguments on various topics and issues can help. Seeking feedback and criticism from people with different backgrounds, experiences, and viewpoints is also beneficial. Experimenting with new and different ways of doing things, such as learning a new skill, hobby, or language, or trying a new recipe, route, or method, can also help you improve your creative and logical thinking skills. Finally, reflecting on your own thinking processes, habits, and biases, and identifying areas for improvement and development can help you become a better thinker.
