You do need to be willing to learn, but unlike what the TrollAccount is telling you, reading Capital is not a prerequisite. Understanding the basics to the extent that you can correctly explain them to others will be a major benefit, yes, but you do not have to have to have read Capital all the way through as some minimum bar where not having done it yet is preventing you from connecting and working with others. The more you know, the better off you'll be, but whatever level you are at, that should not stop you from getting organized. Groups that teach and learn theory in addition to doing real world praxis are the best anyway. You do definitely need to be open and willing to do difficult things, and starting off with a refusal to read a foundational text makes it seem like you aren't ready to do hard work when confronted with it, which I think might be where TrollAccount is coming from. But you still should do what you can, even if you aren't able at this point to read a genuinely long and difficult text. And given what you said in your post, it sounds like you have been trying to start doing what you can, which is good and commendable. But don't preemptively cut yourself off from something (like reading foundational text) because it sounds like difficult work, the whole point is that you have to be willing to do difficult work.

Half of what this other user is telling you is very true, but the other half shouldn't be taken to heart. Another example being where they said "It sucks and is hard and feels bad." It is hard, that is undeniably true. It can suck at times, it probably will in some ways, but in other ways it can and will be extremely rewarding. It does not feel bad, though. Living under capitalism feels bad in general, but getting organized and doing real work actually feels quite good! Feeling good shouldn't be your primary motivation of course, but it should not come as a surprise that working together with other human beings towards a shared goal would feel good to any member of a social species.
