Quote

keep on learning and dreaming and preparing yourself to make your own mark on our world

Is this transalation correct?
不断学习，梦想，准备自己做对我们的世界你自己的印记  

不断学习, 追尋理想而準备把自己的标记刻於世上

夢想 = dream with implication of being unattainable; or if attained but easily disappearing like a dream; never to stay long.

理想 = idealized goals.

想在这世上活出精彩就要不断的学习和追求梦想！
