"If I can't win an argument, I must change my mind." Do you agree with this view?

I can’t win arguments because I’m bad at arguments.

By that logic, I would probably end up changing my beliefs every week or so or end up believing something absurd because someone who believes it is good at sophistry.

But then again, this is also why I try not to argue much. It’s a waste of time and just makes everything worse.

I will, however, hear people out if I think they might have some good points.
