6. Show Up for a Meeting:
Ueda says, “I sometimes cause stress for others by showing up for meetings way before I have to.”
Appear for a meeting; arrive for a meeting. This is often used in the negative as well. Things like, ‘I waited for 20 minutes but she didn’t show up.’
And there is also the noun ‘no show’. Like, ‘We need to talk to the staff. There are too many no shows at the recent meetings.’
7. Way Before Someone Has to:
A long time before someone is required to do something.
‘He turned in his taxes way before he had to’, for example.
8. Be in a Hurry To:
McMillian says, “Are you in a hurry to tell me?”
Do you want to do something quickly?; are you rushing to do something?
We also say, ‘be in no hurry to’ meaning someone doesn’t intend to do something right away. They don’t see the need to do it right away. Imagine you’re having coffee with a friend, they say, ‘Shall we have another cup?’ and you reply, ‘Sure, I’m in no hurry to leave.’
9. Feel Self-Satisfied and Virtuous:
Ueda says, “You feel self-satisfied and virtuous when you’re a precrastinator.”
You feel pleased with yourself and like you’re behaving well.
And Ueda could have said that too, ‘You feel very pleased with yourself when you are a precrastinator.’
10. All Sorts Of:
Ueda says, “That can get you into all sorts of trouble.”
A wide variety of trouble.
Likewise, ‘This store has all sorts of interesting souvenirs.’ Or, ‘You can meet all sorts of people in this neighborhood.’
6のshow upは簡単な表現だと思います。解説中のno showは会議などに出席にしない人のことです。
