Certainly, the statements, taken in context and literally are confusing and if not, conflicting. First, my inference from the first clause suggests his entire life, "up to 30 or beyond". So, what is the significance of age "30"? Second, what is meant by "later years"? Does it mean over 30? If so, the conflict is that in the first statement he enjoys poetry (before and after age 30) and in the second statement he "couldn't stand" poetry "in his later years".
