when someone says,"it is good."

i read a SCM training materials just now, and found SCM is some kind of intersting job that maybe you are willing to devote yourself into it.but the thing is, when you are just an SQE,or even an IQC, the position will only cover a little of SCM, then maybe the job becomes boring, so that really the truth is, the stage is decided by which position you are promoted, standing higher and seeing farther.
i am a green-hand on SCM, and i have to say that i really like that training materials and adore the author very much, so i say, " it is very good". the other thing is , will i give the same appraisement after 1 year's SCM working? and even if i say that it is good also, there is different.the same words, but there are huge distinction back results in it.
