Where I live I get to vote on a lot of things. I vote based on what I think is fair, not what brings me or my country the biggest benefit. In a way I try to be Anti-Nationalistic. Proud to be born and living where I am, but I don't let this cloud my judgement.
I try to criticize every group I deem to be doing wrong things, without being a hater and without taking sides. Be it my country, neighboring countries, Russia, USA, China, groups I disagree or agree with.
Military Service is mandatory where I live, but I made sure not to take part in it. Naturally I am a pacifist, or at least I try to be. Meaning that I am a pacifist, but I think its a privileged thing to be able to be a pacifist.
Be respectful of others, discuss, educate yourself and others.
I try to push and support people or organizations who uncover what I think goes wrong on our world. Tax aviodance/evasion on pacific islands, corruption, inside deals, power grabs, greenwashing, rainbowwashing, pinkwashing, CO2-Certificates bullshit, you name it.
But if I want to be cynical - I don't really DO anything. All I do is talk and write about what I think. I don't really know how I can bring myself closer to my picture of the future - and that's whats fucking scary to me.
Basically, I try to talk about my picture of the future when I get the chance, vote accordingly and try to behave like I would like others to. Be mindful, try to be sustainable, think ethical etc. I am in no way perfect, not at all. I am a first world-citizen. My PCs GPU consumes a lot of power, one of my hobbies is motorcycling, my apartment can be heated all year round. But I don't own a car, live vegetarian and almost vegan. Just trying to find a balance.
Sorry for the incoherent rambling, I really don't know how to answer your question. If I could, I wouldn't need a genie to help me. But if you have tips or your own thoughts, feel free to share.
