Your friend has asked you whether you are satisfied with your job. There are some parts of your job that you don't like, but you like most of it. You say:
Yeah, overall I'd say I am.
"Yeah" is a more casual way of saying "yes".
Say this to agree with something that a person said:
You can also say "yeah" when you're going to disagree but you want to make your disagreement sound a little softer.
"Yeah" sounds less formal than "yes."
You can use the word "overall" at the beginning or end of a sentence. It's used when your general opinion about something is different from your opinion about some of the specific parts of it. For example:
The Canon T2i has some weak points, but overall it's a great camera.
This is how you answer a question or give an opinion, when you're not really sure:
I'd say she'll probably be back at about 2:00.
