Financial freedom is usually understood as having achieved a wealth that allows you to live without working for the rest of your life. I care more about, and already enjoy, partial financial freedom, because years of saving and investing give me a freedom of choice that if I didn't have money I wouldn't have. Besides, since I like what I do when I work, I am not obsessed with retiring. I think that if I had enough money not to work for the rest of my life I would work, at least part-time, or otherwise, in projects that I create.
well.. Financial freedom indeed allows you to enjoy further choices and flexibility in your life. It's giving you the peace of mind knowing that you have a fiscal bumper and the freedom to make decisions without being solely agitated by fiscal scores. The perspective on withdrawal with fiscal is also stimulating. This is happiness.
The idea of pursuing work-related projects indeed after achieving financial freedom is an excellent illustration of using your time and capability to produce impactful things. It's a testament to your drive and desire to contribute to society, indeed without the financial need to do so.
