if you expect the worst, the worst will happen. if you let things bother you, they will. but if you smile, you’ll feel better. studies have shown that putting a cheerful smile on your face can trigger a part of your brain that actually makes you feel happier and more optimistic about the present and future。
如果你总是期待坏的事情发生，那坏事情一定会发生。如果你让事情来烦扰你，那它们一定会烦扰你。但如果你选择微笑，你一定会感觉更好。研究表明挂一个大大的微笑在脸上能够刺激你大脑的一个部分，使你对现在和未来感到更开心和更乐观。
also, feed your optimism with positive reminders. write down short statements that inspire optimism. put them in places where you’ll see them every day, such as on your bathroom mirror, the inside of your locker, and on your computer monitor。
同样，用积极的提醒也可以提升你的乐观。写下一些短小的话语来激励你自己。把它们放在你每天都会看到的地方，比如卫生间的镜子上，柜子里，或是电脑显示器上。
下面就是一些供你参考的激励语：
“anything is possible。”
“一切皆有可能。”
“lead a life of positivity。”
“积极生活。”
“the only thing i can control is my attitude towards life。”
“我唯一能掌控的就是我对生活的态度。”
“i always have a choice。”
“我总有选择的余地。”
“even the longest journey begins with a single step。”
“千里之行始于足下。”
“i will look at the sunny side of everything and make my optimism shine。”
“我会看到每一件事情积极的一面，并让我的乐观情绪发光。”
