What are the differences between "to start off" and " start out" ?
I think they have a common sense which is "to begin to do something" but apparently also they have some unique usages.
Do you think they are interchangeable in the following sentences I excerpted from Oxford Dictionaries.
1.She started out on her legal career in 2008.
2.When the band started out, they couldn't afford much equipment.
3.I started out to write a short story, but it soon developed into a novel.
4.The discussion started off mildly enough.
5.Let's start off with some gentle exercises.
6.We started off by introducing ourselves.
7.I started off working quite hard, but it didn't last.
8.Start out by accessing your list of Applications from your Androids Home screen.
I read this thread about "start vs start off" and the answer is very good but that question does not overlap my question.
