This quote is a profound reflection on the power of our attitude towards life. It suggests that if a person possesses a perverse temper, meaning a disposition that is contrary to what is considered normal or good, and a fretful disposition, which is characterized by constant worry or complaint, they will find unhappiness in any situation or state of life. In essence, the outer circumstances of our lives are not the sole determinants of our happiness or unhappiness. Instead, our inner state of mind, our attitudes, and dispositions play a significant role.

This idea is particularly relevant in today’s world, where the pursuit of happiness often seems to be tied to external factors such as wealth, success, or status. We’re often led to believe that changing our circumstances – getting a better job, moving to a new city, or finding a romantic partner – will lead to happiness. However, if we carry a negative or fretful disposition with us, we’re likely to remain unhappy, regardless of the changes in our external circumstances.

In terms of personal development, this quote suggests that cultivating a positive mindset and working on our own attitudes and dispositions might be more beneficial in the pursuit of happiness than trying to change our external circumstances. This could involve practices such as mindfulness, gratitude, or cognitive-behavioral techniques to reshape negative thought patterns.

Moreover, it also suggests that we should be more understanding and compassionate towards others who seem to be constantly unhappy or dissatisfied despite their circumstances. Their unhappiness may stem more from their internal dispositions rather than their external situations.

In conclusion, this quote serves as a reminder that our happiness is largely within our control, and it is more dependent on our inner state of mind than our external circumstances. It encourages us to cultivate a positive mindset and to work on improving our attitudes and dispositions as a path to a happier life.
