Tired

Recently I've spent more and more time on my part-time job, which is a pre-owned vehicle salesman. With beginner's luck, I've sold 2, first one is 2001 Nissan Quest, second is 2004 Honda Civic. Tomorrow I hope that I can close the deal of the 2005 Toyota Corolla.
It's kinda tired, dealing with different ppl everyday. I'm not a good talker, this job force me try to think more stuff to speak with others, that's what I lack of.
There's a controversy inside my heart now, which way I should go now? Should I send my resume to some financial institutes like banks and brokers, or I just stick with this car dealer business? Some ppl told me just continue doing what I do now, and I can still try to find other job opening, but I have to admit that I'm not a multi-task person, I can only do one thing at one time, sigh! Besides, I still have to finish the oral exam which I escape from last yr.

Anyway, I still have to do some marketing: the website of my dealership http://www.yesnewyork.com If any of you or your friends wanna buy cars, plz don't forget me, my cell phone 347-2042565 thank you.
