"Write four sentences using there is no use doing sth and four questions beginning with Whats the use of doing sth."

There is no use worrying about the past, it cannot be changed. There is no use arguing with people who refuse to listen. There is no use procrastinating, it only leads to more stress. There is no use complaining if you're not willing to take action.

What's the use of studying if you're not going to apply the knowledge? What's the use of exercising if you're not going to eat healthy? What's the use of saving money if you're constantly spending more than you earn? What's the use of learning a language if you never plan to use it?
