I think managing your own expectations. We all want to manage our customer's expectations but, we forget about ourselves. When I get into a business, I know there are going to be a lot of hurdles.  I know there is going to be an issue. When those issues do come, you have to remember, oh yeah, that's what I expected. Instead of getting frustrated and stressed out about it, you work through it. You know it has to happen. There are going to be frustrations. There are going to be things that don't go right. If you can expect to expect the unexpected, you can probably handle those a little better.
