1 . My mother turned ninety. I knew I needed to find a senior _______ center. Not for her — for me. If I were at her age, I would want to stay in shape to _______ life, getting a lot of pleasure. Yes, walking in local parks was my _______, but I wasn’t so active as before.

I called a nearby center, “Do you have aerobics (有氧运动) classes _______ for seniors?” “Sure. Come and check us out! We start at 10 am,” the receptionist (接待员) replied and _______. The next morning, I went there. One part of me was _______ that the class was too easy, not doing me any good. The other part feared it was too hard for me to _______.

When I came into the room, a woman _______ me, “Oh, you’re new. Welcome.” Then the music started. The hour-long workout woke up the muscles I didn’t often _______ in daily walks, suiting me fine. I became a member there. My classmates ranged in age from fifty to ninety. Most gave the exercises their own ________, doing as much or little as they could. ________ no one kept score. Soon I learned physical well-being wasn’t the only ________ there. During breaks, people chatted happily. Whenever some people were ________ we asked around. Were they busy? Were they in hospital? Moreover, we signed cards for those who were ill.

I ________ to be in good shape now as I’ve hoped. Still, I’m grateful for things more valuable from the class — close friendships and new social ________.

2 . The biggest misconception that I've ever heard of is that in order for us to find success in anything, we must be willing to give up something else.    1    .

Over the years, I've come to realize that isn't true. As I grow, I find several things are truly stopping us from living a more fulfilling life. Below are some.

Place limitations on yourself

On the surface, limitations are the things that stop you from achieving something.    2    . You'll keep facing the same problems, forced to make the same choices, and perform the same actions repeatedly. They define your current circumstances and to that extent define your quality of life.

Lack self-control

We all have some aspect about ourselves that we don't like.    3    Maybe you have a large sweet tooth and can't help yourself from eating sweet things. When you have a lack of self-control, those habits are going to remain with you until you find some way to remove them.

    4    

Our ability to come up with creative solutions for our problems comes from our ability to learn and adapt. If you're not learning anything, you're not progressing. Leonardo da Vinci once said, "Learning never exhausts the mind." And I believe it.

Final thoughts

When you get stuck on something, you are never truly stuck    5    . You don't have to be working hard to overcome that barrier, rather change your thinking in how you're approaching the problem. Give it time and keep working at it.
