Change your thoughts, change your life.
The world is an illusion and our perception of it is our reality.
A sheet of notebook paper and a $100 U.S. dollar bill are both sheets of paper! The only difference is we as a society have (agreed) to place more value on one sheet of paper versus another.
What makes January 1st more special than August 1st? It's the agreement we've made that January 1st begins a "new year" which means we put last year behind us and start with a clean slate. We also do this with months, weeks, and days.
We allow events to define time.
Whenever we have a heavy heart it is in part due to the fact that we have (chosen) to limit our perception of options available to us. Sometimes when we are feeling down we go out of our way to avoid "happy people" and sometimes we become upset when people attempt to cheer us up!
This would clearly suggest that in some way maintaining a heavy heart is a (decision) to not want to think about positive things at the time. Whatever we focus our mind on will determine how we feel!
Sometimes you have to forgive yourself and acknowledge your imperfections. People spend less time thinking about us then we realize. The world will keep turning with or without us.
