To me, financial freedom is being able to spend my time on my passion and not having to worry whether it is something that will give me enough money to survive in the short-term. The ability to be able to work on projects from ground up that will not be profitable from day one.
But also the ability to take a half-year holiday with my girlfriend to explore the world, meet new people of completely different backgrounds and better ourselves by being exposed to new situations.
