Continue striving; don’t give up.
戦い続けてください; 諦めないでください。 (tatakai tsudzukete kudasai; akiramenai de kudasai.)
"No matter what happens, just keep fighting."
"何が起ころうとも、ただ戦い続けてください。" (nani ga okorou tomo, tada tatakai tsudzukete kudasai.)
Try as hard as you can.
at the peak of activity or progress
to process and analyze large amounts of data
to make a problem seem less serious
to replace old things or ideas with new ones
to go shopping for a long time until you are tired
