You just need a fresh perspective. Here's some ideas off the top of my head...
Get on your knees, butt or stomach, look around, and start shooting stuff from angles you hadn't noticed before. Now go somewhere else and do it again. Shoot a whole playground from a kid's point of view - a very little kid. See everything towering over you from dirt level. Get to the top of the slide or climbing structures for a better overall view down on the playground, looking down the slide, looking down the ladder - capture a few smiles while you're at it. Get some long-shutter action shots of the merry-go-round, then get them from a position ON the merry-go-round.
Start looking at shapes of things and how they fit together, rather than what they are. Look around for squares and circles and triangles, cubes and spheres and pyramids and cylinders. Find ways to emphasize their shape, rather than their faces and names - disconnect them from 'who' they are.
Find piles of similar objects and fill the frame with them; Tires, nails, screws, people, rocks, leaves - anything. Get tuned in to how they fit together. Place an odd object amongst them and shoot again to emphasize the difference with light, shadow, size, color or whatever way you can figure out to do it.
Do self portraits - by putting the camera in strange places that look up, down or out at you - from the fridge, the dryer, the closet, under the table, hung up in the corner of a room. Reposition some furniture so that the back of a chair is on the floor, then 'sit' in it and shoot the room 'sideways'. Get really creative and put a bunch of stuff sideways as though the wall is the floor and try it again.
Go get one of your friends and get shots of them in mid-air as they jump as high as they can. from various things against various backgrounds. Better yet, get a whole bunch of friends to do it in unison, at your direction. Practice now so that you can do it with whole bridal parties later.
It's all around you - interesting stuff is everywhere - begging for you to shoot it. So shoot it!
