It turned out that there was a course when I applied for the card before, and the coach briefly introduced me to the knowledge of related equipment, saying that I would tell you in detail when you came over for formal exercise one day. Then, on the day I officially went, I felt that there was nothing to talk about, so I went directly to the fitness equipment area to exercise.
As soon as I entered, I saw a group of young men and women talking and laughing and doing their own equipment sports. Because I don't know them well, I'm a little embarrassed and uneasy, but I'll be fine in a couple of days.
It feels good for everyone to exercise together. Later, I went to other different venues, of course, from unfamiliar to familiar. The same experience, even in a different scene, will not feel too nervous.
Sometimes nervousness is related to your personality, but it is not absolute. You can try to change yourself and face everything in your work and life bravely.
