Thank you all for your thoughts. It is especially good to hear from the student's perspective. I feel even more motivated now because these are all traits that I also think are very important and strive to keep with me while I'm  teaching. Good to hear from you all!

Hi Shinhye. I think it can mean more than one thing. It can be like what Steve's comment said. Or the first thing I thought about is that if we have bad memories or too many negative thoughts we hold onto, they can eventually effect our physical health any bodies. For example, if we do not let go of a lot our anger it can effect us physically in our hearts, blood pressure, etc.

What I did yesterday:

My family and I went to the park with my mother's friends and their children. Some of their children are my friends too. We took Balila ( a dish made of chickpeas) with us. They liked it and they asked my mom for the recipe, but my mom said "sorry my dears, it's a trade secret." I enjoyed my time with them and so did my mom.

Thanks

Sounds like a nice day Josul :)

Hope you don't mind I suggested some corrections.

Or you can say: Those cases are rare. If you are talking about a case as in something happening. :)

Hi Sudeep. I actually feel more emotion when I read poetry. Of course it depends on which poem or prose we are comparing. But I think something about the rhythm and increased mystery in poetry ignites more feelings in me. Perhaps this is only because I have an active imagination and poetry allows more ideas to emerge in my mind sometimes. Does that make sense to you?

I want to try to be optimistic.

I found an interesting article.
The title is "Looking on the Bright Side Might Help You Live Longer".
According to the article, optimism is connected with healthier behaviors and healthier ways of dealing with difficult situations.
Optimists tend to take better care of themselves by exercising, eating healthy foods and getting enough sleep.

Doing these things is so simple.
But it's hard for me.
I stay up late at the night sometimes.
I eat junk food once in a while.
I occasionally get angry with my family and friends also.

I want to quit doing these things.
So I'll keep that in mind．
