Children, especially at young ages, are very creative. And creativity can be a glorious(极好的) thing. Look at all the amazing artists and architects that have created glorious pieces of history. Look at all the authors with the award winning books. Now I am not saying everyone is going to end up this way but creativity is an important part of growing up and becoming who you are. This should be encouraged in young children as well as the older children.

Young children grow up playing with make-believe. And so many people try to make their young child see that their invisible friend isn’t real or that talking when someone is not in the room is weird. To adults it is, but for small children it is them being creative. May it be them playing house, or chef, or playing with stuffed animals, it is their creative part coming out. Some kids can have fun playing with rocks and sticks and it’s because of their creativeness that they can do this. The invisible friend part is another part of being imaginative, and is not a bad thing since they will grow out of that phase(阶段). So encourage this and play along with them, play house, or stuffed animals or whatever they want to play. Help keep their imagination running. You can even make up games, like treasure hunts, or dinosaurs, super heroes; there is just so much you can choose from.

All this can help your children’s minds stay creative. The arts and music, even thoughts are an important part of life and important in our society. If we didn’t have and encourage creative thinking, we wouldn’t have had inventors, or philosophers, or as I said before, artists.
