There is a saying:
“Some people die at 25 and aren’t buried until 75.” – Benjamin Franklin
For me, these people literally die before 25, not wait until 25. Cause they just didn’t do anything to be the one who decides his own life. The mark at 25 is just the point everything pumped to them and made them realise: “Oh I’m not able to change anything although I don’t like the things I’m doing”.
Actually, at any age, If you don’t like what you are doing, Change! Have courage to pursuit what you really want to do or even start finding what it is.
Never too late to live the way you want.
