Alot of short sessions

Lately i've been playing multiple short sessions during my day. A short session is usually 40 minutes maximum with an average of more around 20. They've been working out tho and for now they have been good for around 200-300 a session and then I end up quitting and coming back later. These sessions usually consist of me coming in, making a move or two quickly before everyone gets used to my style and then leaving before they figure me out. A good idea for the long run? I dont think so.... but for now it will be ok until I find my rhythm again.
