Respect. Respect is harder to earn and is more valuable. It's "truer" and purer in the sense that it is harder to fake than favor. A lot of people don't like me because of my beliefs and core character, but I'm not going to change those things for the sake of being liked. I refuse to put up a front or wear a mask, so those who like me like me for who I am, and they also respect me. I don't want the respect, though, of people who don't know me fully (including faults and weaknesses). Being liked is fine, and it makes it more pleasant in the workplace, but having the respect of your peers and those above or below you and allows you to do your job without the fear of losing favor affecting your judgment. Making friends and keeping friends is good, but not at the cost of forgoing what is right.
