Hello, the first step is done I got a job in a Call Center in the Customer Service department. The pay isn't the best, but it's okay...Anyhow, what should I do next?

My priority list is: My body(GYM and diet...and clothes I guess). But those are actually extra bills(But I will do it anyways).I also guess that I should open a bank account to save up some money, right?

I am 20 yo, live with my mom, I will not have college debt and I am finishing next year my Industrial Engineer major.

I like to think I am smart, but hehe...anyways in my city there isa big 5 stars hotel, they always have space for sales men, their salary is based on commissions, so when they do a sale they earn a lot of money(they sell vacations, benefits etc, everybody I know that works there is very wealthy). I would like to go there, but I would like to learn a little bit about sales beforehand and be in shape as well(Halo Effect).

thoughts?
