Quitting job is never that easy. I've faced it. After a very long thought, I made a decision to leave and end up getting a counter offer from my company - asking me to stay. I got all the sweat and nice things every employee want to hear from their respective employer, on how valuable they are to the company and letting us go will be a huge blow to them. I think I've already made my mind ..
If the first time you feel like your company cares about you is when you tell them that you could be leaving, it was time for you to leave anyway.
