Learning to play a music instrument or to drawing but it takes time to make the fun start

cooking is always fun, even when it's not good :)

You can try to learn a new language also, this is really a great feelling when you manage your first discussion :)

Having a child is not a hobby and not always fun but it can be a good way to realize yourself; but you need to feel ready for that
