7. Ponder about the past
Looking at your past accomplishments can give you some sort of boost. It can help you motivate yourself to achieve success like before. But sometimes one can get lost in those past memories. Mentally strong people never dwell on their past. Rather, they will focus their time and energy into the present. They want to create chances in the current time so that their future contains more success to bask in. Living in the past fantasies and disappointments is not part of their routine.
