Please correct these sentences and please help me make them much clearer at advance level:
1) Hey Titanic is airing on tv ( I mean shown on tv at present )
You could say that. But just "Hey, Titanic is on. [TV]" is more common.
2) How is life going? OK
3) Have a kickass day. ( can we say this)
4) Have a kickass shift( can we say this).

You might use "kickass" with your friends. But like any word with 'ass/arse' in it, it won't always be taken well by strangers.
