A positive mental attitude is when you look at life's challenges in a hopeful and optimistic way. It means that instead of getting stressed and anxious when things don't go as planned, you try to find ways to see the bright side of things and focus on what you can do to make things better. It also helps you to stay focused on the things you can control, like how you think and act. Having a positive mental attitude can help you feel more confident and motivated, helping you to better achieve your goals.
