Never beg to be recognized by your co-workers that you are a valuable worker.
You have to work in such a way that, in case you leave, they will look at this as at a big loss.
In your mind you capture all facets of the job, keeping them in a perfect balance.
You shouldn't follow those emotional impulses, which blur your thinking and throw you into an emotional turmoil. Instead follow the characteristic guidelines of your job in a creative manner.
Don't try to be the best friend of your boss, because you risk to lose your main objective.
Trough your consistent efforts, attain such a level of a work ethic, that even the walls of the hall in your company "will announce": " This is an extraordinary valuable worker is passing by".

The good reputation is oned of the main guaranty of your removing up the career, and a half the battle at other places of job.
