Hi Calm,
My background is Muslim too.
While you are at work, just be Conscious to any thoughts that are related to i.
Slow by slow, recognition will happen that gossip, lie, taking advantage, trying to prove yourself etc… will be so visible. And that doesn’t mean that not work, you work as you do before yet, not to claim anything.
Most likely, if you these above, ego or survival instinct will hit, what if I lose my job, what if I don’t make enough money or get an promotion etc… , you have to give up all.
Just deeply know that how hard you try, if God doesn’t let you, it is not going to happen.
