There are a few books that help me clear my thoughts...

"Mindset: The New Psychology of Success" by Carol S. Dweck

This is a very good book written by Carol S. Dweck. This book talks about how our way of thinking can affect our success in life.

The main idea of this book is simple: people have two mindsets. One is called the "fixed mindset," where people think their abilities are set and can't change. The other is the "growth mindset," where people believe they can improve and learn new things.

Carol Dweck tells us that having a growth mindset can help us succeed in many areas of life. She gives examples from sports, school, and work to show how a growth mindset can make a big difference.

The book is easy to understand because it uses real stories and examples. You don't need to be a psychology expert to get the ideas. Carol Dweck writes in a clear and friendly way that anyone can follow.

I liked this book because it made me think about how I approach challenges and setbacks. It encouraged me to have a more positive attitude and believe in my ability to learn and grow. It helps me to understand the benefits of having a growth mindset.

In short, this is a great book for anyone who wants to improve their mindset and achieve more in life. It's a simple and practical guide to changing the way we think and achieving our goals.
