甘 (sweet) 呑 (swallow) 苦 (bitter) 吐 (spit out)You do whatever pleases you at the time, swallowing when it's sweet, spitting it out when it's bitter.
One of the most admirable qualities we might possess is self-control. When you have a goal, there are times when you should do something you don't feel like doing, and shouldn't do something you feel like doing. Not as easy as pie?
