Information: Activities, doing things
People probably expect you to go out and do things, like sports, going to clubs and pubs, doing a hobby, and generally being sociable.
You are probably told that exercise is generally a good thing, it helps confidence, protects against stress, anxiety and depression, and is good for your physical health.
But...not everyone likes exercise, or doing things in groups, like organised sports. Some people stay in and are happy with that, they enjoy their own company.
If you want to do more, but lack confidence, or don't know where to go you may wish to think widely about all the things you could do, and try some of the out.
