What is freedom? I believe that freedom is knowing that your neighbour has your back, the land is thriving, and your future is secure.

Good but it still has to depend on your neighbor being a good person. Also, exercising your freedom shouldn't cause damage to your society. Your neighbor might be having your back but shooting up every stranger for made up reasons.
I remember several stand your ground incidents where "law abiding" citizens shot people knocking on their door asking for help.
If you think about it, there's no such thing as total freedom in a civilized society because you have to care about others, even those who don't look like you or live in your neighborhood.
Freedom for human beings really depends on how good of a person you are; how good you are at regulating yourself.

Freedom is in knowing you can take care of yourself, by yourself. Freedom is being alone but not lonely. Freedom is breaking the chains that bind you by not dwelling on the negative and always being positive that this too shall pass.

Per Kris Kristofferson - "freedom's just another word for nuthin left to lose"

Janis Joplin evidently agreed.

Freedom is the knowledge and confidence that everyone can thrive and fulfil their potential, irrespective of race, gender, social background, beliefs, or how much your parents earned.

Freedom is being able to think about your future, and actually make your dream come true
Freedom of thinking and execution
