Oversættelse - Latin-Engelsk - omnis successus in praeparatione positus est

Hi, Aneta,

That "is located in preparation" sounds weird.
What about: "is/starts/depends on preparation"?

It was translated directly from Latin (positus est = is located/situated). In Polish we can say the same too, but, of course, if it is not correct in English we can change it.
Anyway, I don't like: "is/starts/depends on preparation"...
The meaning is a bit different.

Maybe sth like this?
the bottom/point/heart of success is a preparation?

Then I suggest:

"Every success lies in its preparation (the preparation for it)"

Yes, Lilly. I think it is much better. Thank you!
