7. Use other methods to pump yourself up.

Besides remembering positive memories, there are a whole bunch of things you can do to pump up your emotional state temporarily. Here is a small list of such tips within in this list:

Use Music. Listen to uplifting and motivational music.
Use Your Body. How you use your body affects how you feel. Move in a confident way and you’ll soon feel more confident. Move in an excited way and you’ll soon feel more excited.
Use Your Imagination. Close your eyes. Visualize how great everything will unfold. How wonderful and excited you will feel. This is a whole lot more useful than seeing in your mind how everything will turn out badly.
Use Guided Meditation. I like Talking to Win and Self-Esteem Supercharger by Learning Strategies. They are useful for giving you a positive boost for a couple of days.

Use Your Breathing. Not exactly a way to pump yourself up but rather to calm yourself down quickly. Have a look at Here´s a Quick Way to Better Breathing.
7 用其他的方法给自己打气
　　
除那些美好回忆外，还有很多可以唤起你激情的事。下面是一些例子：
　　
音乐——听能够提升斗志的音乐。
身体——让你的身体影响你的感受。充满信心的行动可以让你更加有自信。如果你的身体有前进的激情，你就会感受到。
想象——闭上眼睛。想想你如何见证那些伟大事情的发生。那时的你有多么美妙和激动人心的感触。脑海中这些积极的事情比消极的事情对你更有帮助。
冥想——我喜欢通过“浅谈成功”和“浅谈自尊”来学习一些新战略。他们能给你一些积极启发。
呼吸——它也许不是激励你的方法，但呼吸可以很快让你冷静下来。
