It's easy to tell your family how you really feel about the world around you. It's a lot harder to walk into a meeting, raise your hand, and put yourself on the line. But the hard stuff is what really matters most. And it could mean that promotion you’ve been wanting! The more you do something, the more it becomes comfortable -- regardless of what it is. So tomorrow, start. When a thought occurs to you that you could say, say it. That's all you need to do. Do it once a day until being a vocal part of the team feels less scary. You can beef it up from there. Intellectual, open-minded debates can be invigorating and tons of fun. However, talking to someone who's shoving their opinions down your throat, unrelenting until you admit your unenthusiastic conversion is not. Don't be the person who won't stop until everyone in the room agrees with you. That's not the goal here. Some people have a hard time keeping their opinions to themselves and not aiming to convince the other party. This is often because they firmly and steadfastly believe that they are 100% right. The other person is just being ridiculous -- why can't they see it? Because the other person believes the exact same thing. The odds are that if you're on this page, you're not the "I'm right and you're wrong" kind of person. However, you're probably going to have to deal with this type of person once you're the one going against their opinion. Let them know that their one-sided view isn't conducive to a fun, intellectual debate. There's no point in arguing with someone like this, so don't do it! Once you start voicing your opinion, you're going to run into other people that feel compelled to voice theirs, too. You're also going to run into people that state their opinion and it'll leave you thinking, "Did he really just say that...? I must have misheard." When this happens, don't tarnish your rationale by adding in comments like, "You're acting crazy," or "That's so dumb." That doesn't put you in a better position, nor them in a worse one. It just makes...

TL;DR in Vietnamese:
Hãy thẳng thắn khi ở nhà và nơi làm việc. Đừng nhắm mục tiêu để thuyết phục. Hiểu rằng ý kiến của bạn không phải là duy nhất. Đừng hạ thấp người khác. Lắng nghe người khác.
