Very calm and confident person
As cool as a cucumber
A dishonest or unreliable person
A bad egg
Very easy
As easy as a pie
To sell quickly and in a large numbers
Sell like hot cakes
to have a lot of energy
be full of beans
basic needs of life
bread and butter
Not what one's like or is interested in
not one's cup of tea
Admit that you have said something wrong
Eat my words
When too many people do the same thing, the result won't be good
Too many cooks spoil the broth
To be unhappy about what cannot be undone
Don't cry over the spilt milk
