1 . Smartwatches and fitness trackers (健身追踪器) have gained popularity recently. These tools can record your daily steps, heart rates, etc.     1    . If yes, it might be a sign that you’re addicted to your fitness tracker.

    2    . If you keep setting unrealistic daily goals that involve working out for too long, and if you begin to ignore friends and responsibilities to make time for your workout, then you’re most probably addicted to your fitness tracker.

It’s a struggle to overcome the addiction to fitness trackers.     3    . For example, the number in your smart watch showing how far you’ve come can give you a sense of achievement.

7 . You can always see a beautiful sky at the top of the mountain, but you can’t see it before you reach the top.

Whenever the sun dropped and the blue sky came up, my father and I used to climb the mountain near my house. Walking together, my father and I used to have a lot of conversations through which I learned lessons from his experiences. He always stressed to me, “You should have objectives and capacity like the mountain.” This has largely influenced my life. Without such mountaineering opportunities, we wouldn’t have had enough time to spend together because my father was very busy himself. I believe mountaineering is really beneficial. It gave me time to talk with my father and to be in deep contemplation as well as develop my patience.

Once we climbed one of the highest mountains in our country. It was so challenging for me because I was only ten years old. During the first few hours of climbing, I enjoyed the fresh air, the birds’ singing, and the beautiful dances of butterflies; but as time passed, I got a pain in both of my legs. At that moment, I wanted to quit climbing. Actually, I hated it at that moment, but my father said to me, “You can always see a beautiful sky at the top of the mountain, but you can’t see it before you reach the top. You can always enjoy the scenes of many waterfalls, temples and countless peaks and valleys at the top of the mountain. Only there at the top, can you see all of those things, just like in life.”

At that time, I was too young to understand his words, but after that, I got new hope and confidence. Finally, I found myself standing at the top of the mountain. And there, I could see the whole of the sky, which was as clear as crystal.
