First notebook entry: Introducing myself

What do you think - are English idioms difficult?  Why?

I think the idioms of any language are difficult.  Their metaphorical meanings can be very different to their literal meanings.  I hope you break a leg when you hit the books and get down to brass tacks about learning idioms because, make no bones about it, they can sound like mumbo jumbo - and I'm not pulling your leg and I certainly don't want to queer your pitch.  Remember that Rome wasn't built in a day and if you want to go the whole nine yards you will need to knuckle under, keep your shoulder to the wheel and your nose to the grindstone.

Best wishes and good luck :)
