其实… 我不善于表达 ，其实… 我不善于说出自己心里话…

I'm not very good at expressing, in fact, … I'm not very good at speak their mind …

为什么他们不能不再小心翼翼，而是说出自己的心里话？

Why don't they stop pussyfooting around and say what they really mean?

《柯林斯英汉双解大词典》

说出你的心里话，放开自己并尽可能是发自本能的。

Speak your mind, open up and be as spontaneous as you can.
