What's the age that you intend to achieve financial freedom and why?

Between age 45 to 55. Life is short.

There are many things that I want to do in life other than earning money, e.g. charity, spending more time with family and pursuing my hobby and interest.

Here is everything about me and what I do best.

Well, I really hope by 51 I'll be able to achieve it, there's no true single reason why I set it at 51. But I think for the fact that I started working at 21, probably 30 yrs of slogging (1/3 of my life) is good enough before I decide to do something else that I'm passionate about or to travel the world, perhaps?
