I am just starting out and about to start my first eBay business, I have been excited out of my mind to finally have income coming in after not being able to find a job for almost 3 years. I came across this Q&A on Reddit where some successful eBay seller was answering questions to many people. He said something that has been bothering me, he said that with the new focus on same day shipping that he would be "terrified" to be someone with income only from eBay. This had me thinking if this is really true? Am I starting out on a road that will soon lead me into doom? Am I about to invest a lot of time and effort into something that is going to fall apart and fast? I want my eBay business as my main source of income and my main career, am I a fool for wanting this? I am only 21 and have nothing else going for me, so this has been the only thing giving me hope.
