You know... no matter how positive a person might be, every now and then, life circumstances can make you question yourself and your existence. Life can be very difficult at times... that's for sure.
When things go squirrelly in my life and I start to question myself, I consciously take a "life break" and go some place that lets me see the beauty of the world again and reflect on the positive aspects of my life. In doing so, I start to refocus on what my purposes are in life.
I believe we all have more than one purpose to fulfill in our lives. In focusing in on the purposes of my life I see the value of - me! Seeing my value brings positive energy to me and helps me crawl out of the emotional dumpster I'm in and get back in the game of life with new energy, driven by the things that I have been placed here to accomplish.
Never give up friends - you are far too valuable to so many!
