A long time ago I used a dice with 6 on each side to position myself. The idea was that you can't rely on probability when it comes to communicating your message, any way you roll it; you are guaranteed to come up with a six. Was I really good enough to make a claim like that? Well, I guess I was. Looking back at some of the assignments I had at that time and how I performed in those, I'd say it was not a tall claim without any substance.
I guess sometimes it is good to remember the past. Things are not the same all the time and during the ups and down, doubts are cast over your abilities, sometime by others but mostly by yourself and at times like those, your past achievements can provide you the moral support you need to sail over the rough tides.
