So, I was stuck in my revision last week because I was drowning in stuff like this: MC goes to first period, then maybe we see her at lunch, next she visits with a friend, then at home, and before long, I was bored.
Problem: I was setting up her personality and other important facts in the story, but, I was being TOO linear.
Solution: Ask yourself how your MC would tell this story to her 50 year old friends on a bench in the future someday. Actually, that might not work, but I loved this photo. But asking myself this question did help me remind myself that I am not telling the story, she is. It's first person. So what would she tell me next if I didn't know her story. What would she think was important. What would she leave out, etc...
She'd skip all the mundane junk I was stuck in, maybe summarize some things, and then get right to the next important event.
Tip. No. 1: Imagine your MC is the storyteller, not you.
Duh. How could I have forgotten?
