One thing I have learnt during this time is that one should have backup ready so that not depending on a single income itself. Something financially, one should be doing various things so that in some way or other you can become financially strong. Also saving is important thing now and cutting the credit cards bills in coming years will be important thing.
That's very true. Covid came from nowhere. Lots of people are going to lose their job. Those who haven't any back up plan they will face a very bad period of their life.
After the covid is over no one can predict that when and what crisis we will face in future,
So we must need to setup a secondary financial backup plan to face any such situation in the future.
