<subsection Audience>
You absolutely need to keep your audience's attention. If you see somebody on their phone in the third row, this might be quite impolite but is also (at least somewhat) your fault. You can obviously lose your audience by being too complicated (Maybe try not to use too many technical terms) or by being boring (Don't be too predictable), but you can also lose them more subtle. I can for example help to make eye contact with your audience. Generally try to respond to them (this is a very hard skill to master)
