Summertime is always the best of what might be.

萬物最美的一面，總在夏季展現。

From Charles Bowden.

It was June, and the world smelled of roses.

The sunshine was like powdered gold over the grassy hillside.

It was a song, it was a season.

And I wondered if that season would ever live inside of me.

Today I read an article about the changes between ROS1.0 and ROS2.0 and I want to know more about the application fields of ROS.

Everything has its time and that time must be watched.

萬物皆有時，時來不可失。

There is no perfect time for anything, do it now, otherwise you will regret later.

Just like me, it seems my life had been out of control since I went to my college.

In the past several years, I strived for some changes, better ones, of course, because I haven't given up my dreams, my old dreams to be a useful man who can contribute something good to the world I live in, to the people I love.

But I failed, I failed to make any change, I just muddled along my days.

Actually, the Heaven had generously given lots of opportunities to me, but I let all of them go.

I want to tell myself, the one who is still eager to get better:

"Please do what you want to do now, don't wait, plase grab some of the opportunities, because they don't often come along."

Be prepared to grab the potential opportunities and opt between happiness and pain.
