Strive to get more out of liking things than out of disliking things.
"More", in this context, means "enjoyment", "emotional investment" and "conversational contributions".
By and large, I think I've done pretty good in this arena. However, be advised: following this credo will often put you at a disadvantage in conversations with those who get their pleasure from disliking things, and finding fault and flaw.
--Leonard Cohen, "Anthem"
