What up fam, hope you're dealing with life better than me.
I'm honestly in the same boat. I see people always talking about "Trump, Congress, Media, etc" while meanwhile not only the country but our planet and its ecosystem crumble in its ability to support humanity.
And to level with you, I grew up orphanage poor. I've not had privacy in a home since I was an adolescent, and even though I joined the military to escape poverty and live relatively nice now with a degree and a "good job" I don't feel like anything has gotten better. The system you're talking about definitely caused me to have such a ridiculously tough path, and definitely railroaded me into risking my life in some third world country against people who I never even got to know just to provide for a college education that should've been free in the first place.
As I've gotten older… I've become more inflamed to be honest, and more hopeless overall. Things get worse, and people's only reaction is to say "just vote for someone who won't do X and Y"!. Like dude, are you kidding me? I can't really advocate violence because I honestly don't have the heart to see innocent people die. At the same time, like what are we supposed to do in the face of such reckless capitalist fervor? I'm a little drunk right now, be aware. But as compared to the people around me I feel like I'm the only one sober on a party bus headed for a cliff, and everyone is doing lines while I watch our vehicle get closer and closer to an abyss whose contents I can't possibly predict. I'm sorry I can't give you any more than that friend.
Honestly, making friends is as easy as taking a genuine interest in people. You have to be present in social interactions, and basically show people that you'll be fully present and listen to what they have to say whether it be an opinion or a personal problem. You have to invest in others to have others invest in you my friend. People can definitely tell when you don't give a shit, and those are the folks that I see without friends most often. The ones that think they can do it without others and/or think that others are beneath them in some way or another. I definitely have non-political friends I drink with that don't give a shit about politics, and care more about getting hype on a friday night or selling their collection of 100 genuine yeezies. Doesn't mean I don't look at them as people that definitely have something to offer, and usually that thing is a good time and a good shot to take with me. Find the good in people and hone in on it, or else you're gonna find friends hard to come by.
As for helping the revolution, develop yourself. Develop your political beliefs, just develop your interests and engage and interact with as many viewpoints and diverse casts of people as you can. I promise you, you'll find your purpose for the revolution sooner or later. No one can ask anything more than that of you, and neither should you ask more of yourself. Once you're secure with yourself as a person, you'll find an answer for yourself my friend. Patience and diligence until then.
Don't take it as an opportunity for you to do anything. Get there, recon the people who are in it, and slowly work your way into their confidence so that they can trust your opinion. Until then, if you make any racket you'll just be some dude who has an over inflated sense of importance. Trust me, I've been there in that situation with Socialist Alternative.
Oh boy, fast food… Trust me comrade, I've been in a shit job. I got out of it as a young man by joining the military to escape my poverty. Maybe this isn't an option for anyone because you think you'd be serving imperialism, but a paperwork clerk never hurt anyone as far as I'm concerned. I really don't have a better option for you my friend, other than get good at working people socially and dealing weed. Such is the choices capitalism gives us.
