Nothing succeed, like success

I wanna know what does the phrase "nothing succeed, like success" mean? And who says this and who else say this?

Nothing succeeds like success. Note added "s."

My opinion on the phrase: Once you are successful in one endeavor, it becomes easier to have continued success. Along the lines of "it takes money to make money" and "those that have, get." More on the meaning and origin of the phrase here: www.phrases.org.uk meanings 261100.html and here

I guess once a person has a first success he/she has more resources and confidence and people look upon the person as a winner. Which helps.
