I occasionally meet someone who is desperate to get promoted where it becomes so consuming to these individuals that it can't help but spill out onto other people. If you want a promotion you have to manage it with finesse and never wear it on your sleeve.
If it is out there on your sleeve, you talk about it way too much. You worry about it way to much. You start to focus on the dialog, not the actions. You start to convince yourself you already deserve the promotion and you might get angry at management or your peers. It quickly becomes someone else's problem, not yours. And I have seen people get themselves sick this way.
Go back to basics. Have a conversation with your manager about how you are perceived. Focus on your skills, your strengths and weaknesses and determine what is required for that promotion. After communications, patience, perseverance, performance are key.
Angst adds no value.
I do wonder if this spills over into the life side of the balance under the whining category. 'nuff said.
