On boycotts, I've already started avoiding their products, but when I noticed that people around me, and people in general, don't take it seriously, I began questioning whether it actually has any real impact. Is the problem that boycotts don't work, or that people simply can't resist their habits and desires? I honestly can't create change alone, so what am I supposed to do with that?

So I'm asking: where does an ordinary person start? What common mistakes should I avoid? What genuinely helps, instead of hollow gestures of solidarity?
