It Is Not Because Of "It's time" This Time!

Have job grade upgrading last two weeks, together with the VB letter. This time, only have the feeling of "promotion". Why I say so? because this time only 24 people in the company in the rank M has promotion, and so far I still haven't heard anyone else in my dept is in the list (maybe I am too busy with work until no time to 8). Some colleagues in the other dept congratulated me when met up in lift etc. This time, I only felt...."wow"...
Last year, too many people getting promotion (in my dept) until I felt that it was no speciality. It was just because..."it's time for me", after a few years of experience. Maybe I was affected by a chit-chating with a colleague before I received the letter. From the chit-chating, got to know a younger colleague who is not really met the expectation of an immediate superior at certain task area also get the same promotion. Well, can't blame me I was under-estimate myself in that scenario.
Anyway, now is the time I feel that, emmm, maybe I have something different, hahaha...

P/S: I admit that I am very "responsible" in my job. Can't count how many times I stay late (nowadays normally is around 8pm) in office for work. All this while I don't think I'm a workaholic. Yesterday met a colleague in an activity function, a colleague who rarelly communicate and know well. He congratulated me at 1st, and later sort of saying I'm a workaholic. Well, I can ignore his comment as he really doesn't know me well, nor dealing much in office. Anyway, have a 2nd thought, do I?
