If you ever find yourself in a place, mentally or physically, that you really are not thrilled to be, then I have a bit of a suggestion. Change your perspective. You would be surprised what a difference that can make. And every situation always has an additional perspective that is available. Probably many more than you can even uncover yourself.
My younger brother passed away a number of years ago. I had to give a speech and teach a class less than eight hours after I heard the news. Obviously, I was devastated and mourned the tremendous loss. But that view was not going to help me get to a place where I could perform effectively that day.
So I adapted a different perspective. I realized that Jon had given me a wonderful gift. His death made me realize how wonderful this life is, how grateful we should be for every single day we are on this earth. And how we should never take anything for granted. Yes I still mourned his passing, but the second perspective helped me to see things in a different light.
There is always another perspective available. So choose the one that best suits your needs, best helps you achieve the dreams and desires that you have. That is one of the great wonders of this life. Regardless of your situation, you can always choose a perspective that best suits you.
