1. Time flies : it doesn't. Not always. Sometimes it crawls excruciatingly slowly. Yes, I used a double adverb. It flies only in hindsight when you have the luxury of not feeling like you're tied to chair with a fire lit beneath it and watching an ant crawl across a barbed wire fence and only when the ant makes it safely to the other side can you be untied from the chair. I often used to get this feeling in an Organic Chemistry class.
2. Last but not the least: Overdone, inelegant and gives the feeling of the speaker or writer apologizing when there is no need.
3. Life is a roller coaster: What was the the equivalent of this phrase before roller coasters were invented?
4. You live and learn: Speaking entirely from personal experience - I beg to differ. I like Douglas Adams' take on it - "You live and learn. At any rate, you live."
5. Tomorrow is another day: Well, unless you're The Doctor, it can't be the same day can it?
