Some people are faffers. Mucking about, wasting time, doing all the taks except the one you have to. If you are one of life's faffers then it's OK to faff about before a big project or trip because the percentage of time faffing- a few days, a week maybe is nothing compared to the months or years of a big task. But if you do small things of shorter duration faffing takes over and becomes what you do. So you end up doing nothing with your life. Of course if the big thing has little momentum and is really a sequence of little things the same faffing incursions occur and you end up failing to complete. So, do big things that have their own momentum. if you're a faffer.
