Once you've figured out the high-value items on your To-Do list, you may be wondering how you're going to do all of those other tasks that you haven't listed as critical, but that are still important to the maintenance of your business.
What would happen if NO ONE did this particular task? Would it impact your business's credibility, profit, or customer service? If you can't answer “Yes” to at least one of those categories, then you might want to think about crossing this one off the master list and letting it go undone.
If so, then this is not your core competency, and you should pass the activity on to someone else. Let other people do their thing while you do yours.
If this activity is a one-time deal (installing software, creating an RSS feed, registering a product with Clickbank.com), there's no value in you working your way up the learning curve. Let someone else do it for you.
We often overestimate how much we'll have to pay someone else to do the tasks that we can't or don't want to perform. Get an estimate before you write it off as too expensive. You may be pleasantly surprised how quickly and cheaply an “expert” can handle those tasks that are languishing at the bottom of your list.
If you don't like doing it, find someone else to take it off your hands, pronto. Life's too short to spend your time on activities you detest. And even more important, your displeasure will show in the end result. Do what makes your heart sing and leave the rest to someone else.
