你的心有多大，舞台就有多大。为自己的梦想而努力。加油英文谢谢！！

the stage will always be as large as your heart. Remember to do your best all the time so your dreams will come true for sure. Good luck!
(加油在英文没有真正的翻译....)
楼上翻译的很烂......语法都错了,虽然我的不是很完美,但是比ta好.

The life stage would be as wide as your heart.
Go for your dream.
Go! Go！Go！

用人生舞台更为贴切，“大”字用“宽阔的（wide）”更好
go for 就是努力获取的意思，和后面的go相互呼应
加油不能用refuel，一看就是中国英语，英语用Go表示加油

How much heart you have, the stage has much. Dreams for their own efforts.Refueling ！
仅供参考，语法上有些错误的地方。。

Your heart has in a big way, the stage has in a big way. Tries hard for own dream. Refueling
