Advertising tycoon David Ogilvy famously said, "Hire people better than you are, then leave them to get on with it."
The same goes for your digital marketing. If you want to grow your business and compete online you need to know when a) to let go of things that don't come naturally to you, and b) hand-off the things that you don't enjoy doing. This will free you up to focus on what you love and what you are good at, which is key to sustainable growth.
