Obstacles happen every day...they happen in business...it happens in life. The one thing you can do...is to think happy thoughts. That might sound a little hokie. Sometimes you don't have great days, but there are always great moments. Focus on those, because that will get you through the day.
If you're dealing with a lot of obstacles or problems, you might think they take up 100% of your day. But then you remember what someone said and it made you smile, or the joke that someone said that made you laugh. There is always something good that happens. If you shift your focus, even just a little, your bad day turned into an OK day with some happy moments or your entire day might just be turned around.
So today...go out and think some happy thoughts!!
