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. 1. Return their calls if you were busy when they last tried to reach you. Talk to them. Listen to them. Be there for them.

2. 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. 3. 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. 4. 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. 5. .

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.
