Hang in there!
"Keep up the work" really isn't a common idiom, so I don't have another idiom that means the same. Sometimes you hear "keep up the good work," which means to continue doing a good job, to keep on with the quality you're doing now. However, I still can't think of another idiomatic expression that means the same thing...
It is not an idiom. "An honest day's work" means what it says. It means you work hard and honestly for a dollar or to achieve a good outcome doing your own work at home or doing volunteer work. It means hard work and done well. It also means work not done by crime.
The expression good job can be used to complement someone on a job well done, you made a good job of that. It can also be used to describe the work you do, I enjoy my work, I have a good job.You can also use it to encourage someone to work better, If you make a good job of it there will be a bonus in your pay packet.
teamwork is good Together Everyone Achieves More
Work out a problem.
to continue working good..
it means carry on doing the good work you are doing.
One such idiom is "Don't look a gift horse in the mouth."
To "take the cake" is an informal expression meaning to win a dubious distinction, to be the worst of a kind. It is not used as a compliment. For example: I've seen some sloppy work, but this definitely takes the cake.
To do work and focus
A candle does not have three ends. I think you mean "burn the candle at both ends," which means to take on far more responsibility than you should and be working double-time to keep up.
It's a mountain....Attempting to keep it in "good condition" really wouldnt work out.
