Defeatism is when you feel hopeless and can't find a way to solve a problem. Imagine you are playing a game and you feel like you can't win, so you give up and stop playing. That's kind of what defeatism is like. It's when you feel like giving up on something because you believe that you can never succeed.
Have you ever wanted to do something, like ride a bike or read a book, but thought it was too hard or that you would never be able to do it? That's a bit like defeatism. It's thinking that you can't do something before you even try.
It is important to remember that defeatism can limit your ability to accomplish your goals. If you are feeling like giving up, you can try to talk to someone about your feelings or try to break down the problem into smaller pieces that you can tackle one at a time. It may take time and effort, but with hard work and determination, you can overcome defeatism and achieve your goals.
