"A fool often fails because he thinks what is difficult is easy"

This quote by John Churton Collins is a warning versus overconfidence and ignoring the problem of a job. It suggests that a fool, or someone who is not wise, typically stops working since they believe that something that is actually tough is simple. This can result in them not taking the needed actions to get ready for the job, or not taking the task seriously enough. This can lead to them not having the skills or understanding to finish the task, or not having the right attitude to be successful. The quote is a suggestion to be reasonable about the difficulty of a job and to take the necessary steps to get ready for it. It is also a suggestion to not undervalue the importance of having the best mindset and state of mind when dealing with an uphill struggle.
