Mental Prison

I saw this youtube video some time ago. It made a lot of sense to me in terms of how he explained that most of us live in the prison of our mind. We are the ones who force ourselves to face months or even years of torture by our own doing. We seem to be the worst tyrants of all. If we are not careful, our self-loathing will destroy us. That is why, I am thinking that it is so important to not compare ourselves to others. Now this, I know from experience, is particularly difficult to do. However, happiness is to some degree a choice. We can choose to be in the moment and not to ruminate on what it is that we do not have.
