It's bound to pay.

[Sepmre]

Hi,

I have no idea what may "it's bound to pay"mean here. Could anyone help me to figure it out?

When it comes to success, as my mom used to say, “Stick and stay. It’s bound to pay.”


From the book "Be Obsessed or Be Average"

It means it will pay off in the end.

It's bound to x and it's sure to x are idioms which can be replaced by "it will certainly x".

As Andrewg used in his reply, I would find "It's bound to pay off" more natural.
