"选择一个运动。选择一场革命。并加入它。"

Simplified Meaning:

The quote is encouraging people to find a cause they care about and actively participate in it. It suggests that everyone should look for something they are passionate about, whether it's related to the environment, social justice, or any issue that requires change. For example, if someone is very concerned about climate change, they might join environmental groups, participate in clean-up drives, or campaign for policies to reduce pollution. Being part of such efforts not only helps bring about needed changes but also gives a sense of purpose and community. It's a way of contributing to society and making the world a better place. Instead of just complaining about problems, taking action can bring real solutions. Therefore, anyone can apply this wisdom by identifying what they care deeply about and finding ways to support and promote those causes actively.
