Stop giving excuses and focus on getting the job done. In the first case, no one is pointing a gun at you to ask you to join this company. If you think sales is an easy job, please do not waste ppl time, go look for a service job and be contended to wait till end of the month for your fixed salary.

Hitting target is part of the sales job, not everyone is born to be that. You think the title is good or driving around Singapore is an easy thing, please think twice.

If you don't open up to your colleagues, why do you think they know what type of help you need. And stop procrastinating that everyone staying there are waiting to leave, like you. Every person has their own abilities to survive and they have their reason to stay around too.

Don't waste time pursuing your degree, your attitude must change first.
