It's what you do next that counts, not what happens but what you decide to do about it.

重点不是发生了什么，而是接下来应该如何应对。

It's not what happens to us counts, it is how we respond to it that counts.

Maybe that can explain why so many people consider attitudes are one of the important factors when it comes to evaluate someone's performance.

Our attitudes shape our feelings, beliefs, and very often our behaviours.

Our attitudes, while sometimes indifferent, are often either positive or negative.

They play a big part in life, which at times can be immensely harsh.

Things and events will happen over which we have no control.

For some of us, we may accept the harsh realities and blame our circumstances.

But for the other part of us, we may think harsh realities are not accepted. We just recognize that we always have a choice as to what attitude we want to embody. Each and every day. And in the end, we succeed.

So please have a positive attitude, please choose to react positively to what happens to us.

No matter what happens in the future, we still can make some good changes to have a better result.

Worse than not realizing the dreams of your youth would be to have been young and never dreamed at all.

比未能实现年轻时梦想还糟糕的是年轻时根本就没有梦想。

From Jean Genet.

Did I have any dream when I was young?

Certainly I had. But I can't remember what it was.

That might shows I didn't have any detailed plan to realzie my dream.

So, with time passed, my dream has faded away.

And now I have dreams, I still want to make some of them come true.

But I doubt whether my ability can support my dreams.

Raise a question now: what are differences between ROS1 and ROS2?

I hope I can give a detailed answer before 12 o'clock next Sunday.
