I am the same way! Unfortunately, this has cost my family a lot of money over the years because I used to decide I was going to be the best (insert whatever company) home representative EVER! I'm going to save my family from financial ruin, earn that new car, win a trip to Jamaica for being the top salesman, etc. then after about two weeks, I'm done. I have no desire or interest in the product, company, or whatever bs prize they dangle in your face.
I do this with everything I start, but that one area has financially hurt us. Like the time I was manic and applied for a credit card without my husband knowing and ordered thousands of dollars in product that I 'had' to have to be the best consultant that company has ever seen. 7 years later, I still have boxes of unopened product.
