Little things keeps you going.

Everyone has their own crunch times: projects, work, personal issues.  Unfortunate, but it always happens, there will always be times like this where you get crushed under the onslaught of multiple problems and issues.  When I encounter these, I think of one particular Chinese saying.

苦中一點甜 

Its not anything awe-spiring or telling people the meaning of life.  All it means is "A bit sweet in the middle of bitterness". As it implies, it is used to refer to the little bit of good thing when your life goes into crunch mode.  It doesn't tell you to take an easy way out, it doesn't give you advice on what to do, it is used to describe that little bit of nice things.  

For me it reminds me to take a breather, despite the pressure, take a quick breather now and then.  Do something you enjoy, and continue on.  That "苦中一點甜" is exactly what is needed to keep you working.  

Take some time, drink some water, get a snack, and continue on.  Work hard my fellow exam time students :)  

Even though I do not particularly love sweets, a little sugar in the middle of an overload work is always helpful.
