I think I'm going to mention a nice pension
It's good to have a nice pension but why would you want to talk about a nice pension?
I walk them to know that working hard will pay off in the long run.
It is great to get a good pension and be proud of it. It is good that you let others know that working hard pays off.
I am glad you agree with me.
Hard work does pay off in the long run, and you are a good example of that. Once you retire, all the people in your social circle will wish they had done what you did.
