I plan on quitting my job without any notice.
Why would you do that?
I really just can't stand it anymore.
It sounds like you're very frustrated. There are procedures in place to resign your position. You should follow them in order to get another job.
Nah, I don't want to work anymore, I'm just going to quit and find another job.
I recommend not doing this. This could possibly affect future career options that you would have down the line.
