There was a big hype a while back about how people just wanted to keep it "real". And they would say all kinds of things that, while possibly true, possibly honest, were not constructive or helpful. I love this word "sincere" because it means honest but with a connotation of construction and well-intention. I think if you want to pick whether to be honest or sincere the latter will probably take you a lot further, other things held equal.

I've been amazed how in the US being sarcastic and stretching it to the limit - specially in work places - was seen as "the norm" and "how you should be".

The result is that very few people trust very few people (and that trust is not very large, its more of a way 'i know this guy who do XX because I have leverage').

That's sad. Working in a sincere environment, with good values, is so much better on so many accounts. And it also pays off. Have courage. Be sincere.

Absolutely, and sometimes sincerity is so unanticipated in certain situations that it may be interpreted as some kind of ploy.

But I agree with the post. It's worth it to be sincere. Even when those around you may not be expecting it.
