When can you be late?
- At a conference, you can be late and not miss too much from a speaker’s notes; if you get to the last part only, you can pretty much get the idea of how the speaker is, and if you’re only late for 10 minutes, at the beginning, you won’t miss much;
- At a meeting, a lot of times, the first 20 minutes is warming-up; you can skip it; even though a lot of meetings are a waste of time, you can decrease your own loss;
When not to be late? When other people depend on your presence there – one-to-one meeting, for example.
Also, whenever possible, leave early; change the scenery; fast.
