easier said than done
more difficult than you think
When pigs fly
something that will never happen
(to) keep one's chin up
to stay positive
(to) hang in there
to persevere; to not give up
(to) live from hand to mouth
to barely have enough money to survive
Got canned
To lose your job/to be fired
(to) think big
to set high goals
last resort
if there are no other alternatives left
right-hand man
to be the most helpful assistant or employee
if worse comes to worst
in the worst case; if absolutely necessary
(to be) stressed out
under severe pressure; very anxious
to) stab someone in the back
to betray someone
What's the matter?
What's the problem?
