Too many of us spend a lot of time doing things that don't bring the value we are worth. In life, we spend time doing things we think we half to do - not because we want to, or like doing them. What we don't often think about is the fact that we could likely pay someone to do the "things we half to do", and use that time to make far more than what we are paying out.
The Duct Tape Marketing Blog has a great post on that:
Another side of this is in our business when we get stuck doing busy work. This might be things like paperwork, sorting information, filing etc.. You don't get paid your for these things. You get paid for setting appointments, sharing your business and products with other people, and leading your team. Do the things you get paid for. Other things should either be skipped (if not important), passed on (to someone who can do them also), or hired out (to an assistant - even a virtual assistant). This will give you more time to focus on what you get paid for.
Now if you enjoy doing some of the "busy work" activities then by all means continue to do them, however don't call that business time and effort. Call that your fun time.
