1. Pride
“Young men, do not be too confident in your own judgment. Stop being so sure that you are always right, and others wrong. Don’t trust your own opinion, when you find it contrary to that of older men, and especially to that of your own parents. Age gives experience, and therefore deserves respect.”
2. Love of Pleasure
“Youth is the time when our passions are strongest—and like unruly children, cry most loudly for indulgence. Youth is the time when we have generally our most health and strength: death seems far away, and to enjoy ourselves in this life seems to be everything. ‘I serve lusts and pleasures’, that is the true answer many a young man should give if asked, ‘Whose servant are you?’”
3. Thoughtlessness
“Not thinking is one simple reason why thousands of souls are thrown away forever into the Lake of Fire. Men will not consider, will not look ahead, will not look around them, will not reflect on the end of their present course, and the sure consequences of their present days, and wake up to find they are damned for a lack of thinking. Young men, none are in more danger of this than yourselves. You know little of the perils around you, and so you are careless how you walk. You hate the trouble of serious, quiet thinking, and so you make wrong decisions and bring upon yourselves much sorrow.”
