意識の差が結果の差をもたらすって英語でなんて言うの？

結果は意識によって左右されるものだ
depend on は、～よる、～次第だという意味があります。

彼の = his
意識の差 = difference in consciousness
他の社員 = other office workers / other office staff
とは異なる = differ from / be different from / vary / be unlike
結果の差 = difference in results
もたす = be gotten from / beget / result in / lead to

この例から、いろいろなコンビネーションができます。

The difference in his awesomeness led to a difference in results from the other staff.

His difference in consciousness resulted in a difference in results from the other office workers.
