Ebay seller mentality

I don't know about the people who make ebay a business, but I know that the few times I have sold something on ebay I check my listings many times a day. What makes me do that? the item doesn't close for 4 more days, but I check it 3 or 4 times a day, every day. I do it even though I know most bids come in the last two days. Still, I check the counters and see how many people are watching the item. will they sell? Will my watching the pot prevent it from boiling? I'll know in 4 days.....
