翻译：机会总是迎接那些有准备的人。

Chances are for those who are ready to catch them.

这句话应该是源自西方，原作者是法国著名的生物学家Louis Pasteur，出生1822年。
原文是： Chance favours the prepared mind.

当然，这里的chance有点指几率，但是也有机遇的意思，毕竟机遇很多要依靠几率。如果你觉得不准确，可以改成：opportunity favours the prepared mind.

opportunities are prepared for those persons trying to get.

Opportunities are always awaiting those people who have prepared for them.

There are always opportunities for those prepared to meet the people

Opportunities are always for people prepared to get them.
