“不要去幻想会发生奇迹” 英语怎么说？

Don't just dream that miracle will be up on you! (You really need to work for it or earn it).

I believe that this the true meaning of the translation.

Do not fantasize can have the miracle

Do not have the illusion that there will be a miracle.

Do not expect miracle.

Do not fantasize that miracles can happen.

It's impossible that a mircle will happen,if you are just a fancinater.
