改错.If you sure it you want to ,just go for it.

If you sure it you want to ,just go for it.
是不对,你从句里边没有谓语,sure是形容词或者副词,不能做谓语的；还有,句子的意思也不通.我觉得应该是这样：If you are sure about it,and that's what you want ,just go for it.
OR
If you are sure (that) that is what you want,just go for it.这里,括号里的that可要可不要.如果要,则它作为后面从句的引导词；如果不要,则是省略了从句的引导词.

正确表达：If you ARE sure THAT you want to ,just go for it.

If you are sure you want to do it, just go ahead.

if you sure what you want to,just go for it
