Stupid people

I told my dad:"some people are really stupid" of coz i was talking about those people i'm training. they keep asking stupid questions and never learn. when i was saying that. i felt my nose getting sore and agitated. this is how hard i worked towards this point. it's been six months and i became the most senior reporter in the company, while four competitors resigned. they were stupid so they are off. and the company should really feel great having hired me because of what i have done and what i will do for the company. when i am now training people, the questions they are asking is really the questions i had nobody to ask. my boss at the time was so cold and she expected me to know everything or i'm too stupid to work here. and now i became evil instead of learning lesson from my boss and treating juniors better. yes it's evil but where else can i vent the steam. i told my dad. i am really smart and i felt so excited about it. but all these is only to convince myself i'm doing the right thing while the job has alreay made me sink into irrevertible challenge in life and depression.
