Peter Drucker said there are only two profitable endeavors of a business. Marketing and innovation.
If you're spending most of your time managing your business, your business will probably fail. The vast majority of your time should be spent marketing it, promoting it, and testing your approaches, methods, tactics and so forth.
At the same time, if you can create a new or better way of doing things, something no one else is doing, or you create a brand new product no one else has, then that should be highly profitable for you.
Are you waiting by the phone for it to ring? or are you actively pursuing business on a daily basis?
What problem can you solve for others that hasn't been done before?
