Take care of your manners as seriously as your money.
Woe to he who acquires wealth, but forgets to care about his manner towards people. It is true that money brings respect. But without good manners, that respect will ONLY be because of what they need. Manner is not only about how we treat others, but everything about our actions (how we eat, walk, bring ideas e.t.c). Your manner defines you, make it good.
