A few things to do during weekends to improve your life
Weekend at last! Something you're so looking forward to after a tiring week at work. Here are several tips on how to make the most of your weekends.
Spend time with loved ones. Reconnect with family members or friends you neglected(疏忽) lately. Don't do it out of guilt or because you have to. Do it because you want to. Reach out to them to see how they are doing. {#blank#}1{#/blank#} Return their calls if you were busy when they last tried to reach you. Talk to them. Listen to them. Be there for them.
{#blank#}2{#/blank#} Stay away from TV, iPad, iPhone and any other electronic devices. Unplug! Your brain needs to clear up from all the stress you've put on yourself during the week. Why not read a book instead? A paper one. Seriously, when was the last time you did that?
Laugh, laugh and laugh again. You can never have enough of it. Laugh is the best medicine ever. {#blank#}3{#/blank#} For example, it helps you manage stress, strengthen your immune system and you are 40 percent less likely to suffer a heart attack.
Express appreciation. {#blank#}4{#/blank#} Be grateful for your family, friends, health, the food you put on the table, the clothes you wear and the air that you breathe.
There you are. Doing a few things during weekends will have a positive long-term effect on your life. {#blank#}5{#/blank#}.
A. Apply the “no technology” rule.
B. Pause and pay attention to your thoughts.
C. Friendship is the best source of happiness.
D. Don't call them only when you need them.
E. Put them into practice and you'll beat the Monday Blues.
F. It benefits your mental and physical health in so many ways.
G. This is something you should be doing every day, not only on weekends.

I had to knock on the taxi to get his attention. Finally, the driver, a man about 60, looked up from behind the wheel and apologized, “I'm sorry, but I was reading a letter.” He sounded as if he had a cold or a cough.
Since I was in no hurry, I told him to finish his letter. He shook his head, explaining that he had already read it several times and almost knew it by heart. Curious, I asked whether it was from a child or maybe a grandchild. “This isn't family,” he replied. “though he might just as well have been a regular member of the family. Old Ed and I grew up together.”
They were always friends. But since he moved away from the neighborhood 30 years ago, it'd generally just been postcards at Christmas time between them. A couple of weeks ago, Ed died. “I should have kept in touch.” He repeated this, more to himself than to me. To comfort him, I said sometimes we just didn't seem to find the time. “But we used to find the time,” he said. “Take a look.” He handed the letter over to me.
The first sentence “I've been meaning to write for some time, but I've always delayed it.” reminded me of myself. It went on to say that he often thought about the good times they had had together. When I read the part where it said “Your friendship really means a lot to me, more than I can say because I'm not good at saying things like that”, I found myself nodding in agreement.
We had gone several kilometers and were almost at my hotel, so I read the last paragraph: “So I thought you'd like to know that I was thinking of you.” And it was ended with “Your Old Friend, Tom.”
“I thought your friend's name was Ed,” I said.
“I'm Tom,” he explained. “It's a letter I wrote to Ed before I knew he'd died. I never put it in the mailbox. I guess I should have written it sooner.” His face was pale as he wiped his eyes with a handkerchief.
When I got to my hotel room I didn't unpack right away. I had to write a letter and post it.
