But there's a huge difference between feeling overwhelmed at work and feeling overwhelmed when you were in school - in school you had to push forward and do all your work yourself until it was done. Now - you can just pay somebody else to do your work for you!
So why don't you?
Not only will you feel a huge sense of relief once you begin offloading jobs to somebody else, but you'll be able to focus on doing the jobs that only you can do! And that's the key to growing your business - handing off the mechanics so that you can focus on the core of your business.
