Don't let yourself live like a joke. What does this sentence mean?

As an individual, don't do stupid things in this world and do things that are unacceptable. In fact, you don't have to care too much about other people's opinions. You only need to have your own independent thoughts and ideas, and through your own personal experience and practice, you can improve and achieve your goals. There may be some stages that others don't understand, but you just need to stick to it and know that success is a lonely intention.
