1. My effort is paid off.
Is this sentence correct?
How can you use "pay off" and "effort" in a sentence, would you please give me a few more examples, thanks.
2. How do I use the word "discipline" about teaching children?
John, you are naughty, you need more discipline. (does this sentence sound good?)
Children in grade one at this school don't have discipline.
Do they sound correct? If you can give more examples and clarify to me, that would be very good. Thank you :))
