I think a key to streaming is balance of audio and visual "stimulation." If you're not "doing" (as captured by OBS) something stimulating then you need to be saying something engaging. Some in theory if you're coding in python you might need say something to engage your; teaching, explaining your methodology or talking about current events around technology. If you're confident your audio stimulation will not be as strong you need to visualize something engaging. Sometime I did once via youtube was streaming myself writing a research paper creating maps in arcgis.
