“Endo-san thought the world of the president and was deeply saddened when she retired.”
Come up in the world
To gain status, power, and/or money
“Takeuchi-san has really come up in the world since we last saw her 10 years ago.” Note: To “come down in the world” is to lose status, power, and /or money.
Out of this world
Very impressive, incredible
“Tell Mieko-san that the fashion journalists thought her new dress designs were out of this world.”
On top of the world
Extremely happy
“Nagano-san is on top of the world today; she just found out she has been named “Employee of the Year”.”
It’s not the end of the world
Cheer up, it isn’t as bad as it seems
“You didn’t win the design contest, but it’s not the end of the world. There’s always next year.”
