"Showing a return"

[Noriko Tan]

I'm not sure about the meaning of the following sentence:

"I know it’s difficult to swallow the idea of pumping money into something that’s showing a return yet"

I mean, why it's difficult if something is showing return?

or should it be: "...into something that isn't showing return yet"

For further context, check out this source article (under the subtitle "4) Learn to delegate")
Thank you.

It should clearly have said "something that's not showing a return yet," but the author evidently skipped a word in typing.
