Boost your current income
Maybe by creating a source of passive income or starting a side business, investing your money, etc...

Kumar: Rajesh, How is your new job going?
Rajesh: I am very much satisfied with it.
Kumar: My friend, you should never feel satisfied with your first job.
Rajesh: What shall I do then? Leave the job and start looking for a new one?
Kumar: No, I am not asking you to do that but what I want to convey is that you are in your 20s right now and you should constantly keep looking for the ways to earn more money. Maybe by creating a source of passive income or starting a side business, investing your money, etc.
Rajesh: But I have enough earnings right now.
Kumar: I am not asking you to earn more for yourself but for your future self.
