My friend Wayne in Canada, (not to be confused with our mutual friend Wayne of the same clan in Ireland), was asked to do a short article for a McGill University publication. He ran it by the other Wayne and myself, did some serious editing and came out with a good piece. He said when it gets published he was putting it in his "Wayne is Great" folder.
What a brilliant idea. I had never heard of it before. Every one of us needs to keep an "I am Great" folder and add things we have accomplished that we can be proud of. All of us at times fail and we can get down on ourselves. Our friends and family reassure us we are not hopeless failures (well, my friends anyhow; my family not so much - just kidding) but if we have a "I am Great" folder, we can look back and reassure ourselves that we CAN DO!!
And ask your family and friends or co-workers to suggest stuff to put in it. We don't always remember what we have accomplished, being focused on the tasks remaining. If it is written, put a copy in the folder; if it is something you have built, put a picture in along with details. Figure out some way that is meaningful to you.
I know some of the things that are going in my "Al is Great" folder. From times long past, it is likely to be just a list of things that I will add to as I remember. For more recent accomplishments, it will be documents and pictures.
