I started reading this book called Mindset: The New Psychology of Success by Carol Dweck. Although I just started reading it, I feel I am gaining new perspectives on my attitude and behavior. You are never too old to change the way you look at things, how you handle situations, or how you relate to others. A growth mindset, where you feel intelligence can be developed, is something to always be working on. It's definitely not easy but working at embracing challenges and learning from criticism is key. Always strive to learn about yourself and how you can help others.
