Do you agree with the speaker when in lines 17-24 he says that we add to our own misortunes?

Yes, I agree with the speaker's assertion that we often contribute to our own misfortunes. Many times, our choices, behaviors, and attitudes can lead us into negative situations or exacerbate existing problems. By recognizing our role in these outcomes, we can take responsibility and work towards making better decisions for our future. Acknowledging this can empower us to change and improve our circumstances.
