When I was working I also had this going on. I was always beeing pressured to not do so much or learning more things. I hated that others were lazy and wanted to just do the minimum amount of work to meet their quota. I was always the one they asked for answers as well. Everyone had the same info. Everyone hated me in the depts cause I made them look bad. So they said. I just told them I wanted to achieve more and move up in the company unlike them who just wanted to get stuck getting paid the same and never move up. Now that I look back at this I do realize that it was the BP talking and thinking. I still think this way though. The only thing that I can say is that I actually did get promotions even when I was the only one that had no experience or less time at the job that got promoted. Your not alone.
