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.

爱因斯坦花了九年时间才在学术界找到一份工作

爱因斯坦在苏黎世理工学院(Zurich Polytechnic)的几年里表现出了一些闪光点，但他叛逆的性格和逃课的癖好，让他的教授们在他1900年毕业时给他的推荐信不够热情洋溢。这位年轻的物理学家后来花了两年时间来寻找学术职位，最后在伯尔尼的瑞士专利局找到了一份工作。这份工作虽然卑微，但对爱因斯坦来说却是一份完美的工作，他发现自己可以在几个小时内轻松完成办公室的工作，剩下的时间用来写作和做研究

1905年——常被称为他的“奇迹年”——这个卑微的职员发表了四篇革命性的文章，介绍了他著名的方程式E=mc2和狭义相对论。尽管这些发现标志着爱因斯坦进入了物理世界的舞台，但直到1909年——在他离开学校近十年之后，他才获得了一个正式的教授职位。
