Answer:
Showing not telling.
Explanation: [I'm 13 btw]
As a young writer, I've experienced difficulty with this ''show not tell'' thing, I'm still experiencing difficulty with it till this day. But now it's a lot more easier to describe the five senses (what the characters smell, hear, or what the characters see), how a particular place looks like, or how the characters feel throughout each scene.
Showing instead of telling can help the readers reflect what the characters are feeling. Whether they are sad or angry, happy or disappointed, showing is better than telling.
I'll give you an example:
Telling:
Jane is feeling hot.
Showing:
The atmosphere of the room was so thick, that sweat showered Jane's hair, her clothes were slightly damp, as she paced up and down her room.
It's better when there is more action described than dialogues. Yes, dialogues are important, especially when characters use them... But try not to overuse it. Otherwise there is a lot more telling than showing. Try to mirror the emotions to your readers. This way your readers won't fall in a long slumber.
