Invest in your outsourcing education.
If you’ve never outsourced before, or you’re not sure what you can offload to someone else, experiment. Invest a small amount of cash in outsourcing something small. If you don’t have anything small, make something up. If it’s admin, get someone to put all your business cards into a spreadsheet or database, if you’re looking for design work, get someone to design a logo, if it’s proof reading, send over a short document with deliberate minor mistakes. You get the idea. The point is to see what works for you, and to get used to letting go.
