I think the answer is we should do what Allah says to be preserved from the hell fire. And in this verse, it mentions about one of that ways. It is about Ramadan. 

We can understand that if we don't want to go to hell, we should pay attention to our attitudes more in Ramadan. First, we have to pray best and fast in Ramadan. Additionally, we shouldn't say bad words, make fun of someone and such kind of bad things. We should help people or animals that need help, greet the people we see and like our prophet said we should smile all time. We ought to thank to Allah every time for everything. 

Like I mentioned first we should pay attention more to these things in Ramadan.
It can break your fast if you say bad things and make bad things. So, I am trying to be calm when something annoys me. In Ramadan my daily routine is not much different than the other days.  I wake for sahoor and fast. I read Quran everyday also I pray regularly. But they are not just for Ramadan I do them every day. And I do my homework like every day then I make iftar and watch TV. Like I said it is similar with my daily routine. But to me, I should do more.
