Sincerely, I would like to tell you that I am truly sorry for everything that has happened to you over the course of you time with trying to sell cell phone parts. I know that this is not a very lucrative way of doing things, but you need to understand that the truth about all this information is that you need to be a little better at selling products. Being a salesperson happens to be one of the only jobs that has he least amount of satisfaction and there is good scientific reasons for this. The first is that you are working to try to push things on people. That is never fun. People are usually resistant to a salesperson and that is not good for you because you are a salesperson. It is also not good because you are a person who needs support and you need to be the one who works with a lot of people to make your job better. You also need to know that you are going to work somewhere for at least 5 years and then you are going to be in a different bracket. And by bracket I mean a different salary bracket. You want to be able to understand that there are a few people that you are working with in this capacity to better yourself and your work. I want you to think long and hard about the possibility of moving up a bracket and going to try to sell electronics at a big box store.
