1. Use tasks to enter into new narratives.
So you like to fly. Fly where? A destination provides an opportunity to connect the task of flying with a new scene. So fly to the Moon. Or to Australia. Or to Narnia. Anywhere, but somewhere that will extend into more storyline that is compelling to you. Same with summoning a person or object. How does this new element create new things to explore? A conversation with the person? A magic trick with the object? Look at each task as opening doors to new things, rather than checking off things-to-do. Another easy way to create a vibrant scene is to borrow from fiction that you like and then re-create it.

2. Keep it open-ended.
You can and should always fall-back on the general attitudes of "talk to someone" or "explore the environment with your senses." This mindset can provide endless improvisation and new experiences. If you don't know what to say, just say what you feel. Grab the nearest DC and confess what you are thinking and feeling right then. If you don't know what to explore, look at the plainest things: the sky, the ground, your own body.
