We know its politically incorrect to call them failures. We’re of the school of thought that if you put them in a negative connotation you will be more like to try to improve on them.
And that is what we want you to do. Once this list is complete note what you tried and should leave alone. Then look at what you attempted before and try again. Remember just like sacrifice, failure only has to be temporary. Learn why it didnt work. Fix it. Then make it work!
