I have been thinking about it for weeks. I even wake up sometimes earlier than my alarm clock just to ponder on that. I know that there is no perfect job. Currently, it’s neither making me physically sick nor giving me hard times. It’s just that, I don’t feel like staying in that job anymore. A foreign friend once told me that if I feel like I am no longer challenged professionally, then I should quit. Is that somehow a basis or am I just exhausted to think this way?
