I have decided to steal a coworker's ideas and turning it in as my own.
That's pretty sleazy and totally unethical. Why would you do such a thing?
Because my ideas suck and his do not.
It sounds like you may need some help at work. It's improper to steal someone else's work and pawn it off as your own. If you are caught, you could get fired.
I agree completely. I just want to steal from people and get away with it.
If you insist on operating with that philosophy, you won't last very long on any job. You need to step back and refocus your efforts at work. Be constructive: study and get up to speed on the projects and soon your own ideas will rise as high as your coworker's.
