Every morning dedicate a few minutes to thinking on how was your yesterday, what you want to do today, and what is important to do. How today will differ from any other ordinary boring day? Plan something and complete it, it will bring you pleasure and will make you proud of yourself.
Set a goal you need to reach during this day. Unsuccessful and unhappy people often have a feeling that their days are all alike. All people have the same hours in the day. So how will you spend your 24 hours? What will you do today to make your tomorrow better?
