In the absence of clearly-defined goals, we become strangely loyal to performing daily trivia until ultimately we become enslaved by it. -Robert Heinlein
Setting goals is difficult because it is almost exactly equivalent to determining what your life is about. The problem is that we tend to avoid hard things like figuring out what our life is about and fill our lives with easy things like answering email. Only later do we realize that a big stack of easy things done almost never equates to getting just one of those hard things, those big things done.
Don't have all your goals figured out, yet? Welcome to the club. Instead of beating yourself up for not having those goals figured out, how about giving yourself a small taste of getting something done towards that.
Today pick just one of those big things you know would be on your big list of goals and work on that for just one hour today. You might miss the flurry of other activity, but you sure are going to like seeing what you might accomplish once you jump over your unnamed fear and put in even one hour on something that will make a difference in your life.
