以下是一篇英语励志短文：
"Believe you can and you're halfway there." This quote by Theodore Roosevelt has been a source of inspiration for many people throughout history. It reminds us that our thoughts and beliefs have the power to shape our reality.
If we believe that we can achieve something, then we are more likely to put in the effort and take the necessary steps to make it happen. On the other hand, if we doubt ourselves and our abilities, we may give up before even trying.
Of course, believing in oneself is not always easy. We all face challenges and setbacks along the way. But it's important to remember that failure is not the end – it's an opportunity to learn and grow.
So if there's something you want to achieve, don't let fear or self-doubt hold you back. Believe in yourself and your potential, and keep pushing forward. You may be surprised at what you can accomplish.
