Self-Challenge Tanked

Have you ever noticed that when you try to set a goal - let's just say finish a shrug by Friday - that you will find yourself too busy to even knit? From like, the minute you decide to start your new challenge until you realize it's hopeless and you will NEVER finish the item? Life has conspired against you in a huge cosmic way so that not only can you not finish your project, you can't even find time to pick up the needles? Yup, me too.
