It is so easy for many people to just wake up and focus on the negative things in their life. But look at everything you complain about today in a different light. Put a positive twist on everything.
If you have a job you hate, just stop and be thankful you have a job to hate. Hate sitting in traffic? Be thankful that you have a car to sit in traffic in.
It is so easy to but a positive spin on anything going on in your life. I remember being fired from a job years ago and my wife and I going out to dinner that night to celebrate that I was now free from that stressful job.
Just give it a try. What's the most that could happen other than you are more happy that before?
