I gave a marketing presentation a couple of weeks ago and shared 4 painful lessons that I've learned after 17 years of business ownership. Please pay close attention to them. Follow them and you'll prosper. Ignore them and you'll flounder and eventually die as a business. 

As the business owner your primary job is to market and bring in new business.

Everything else (SEO, Web Design, Email Marketing, accounting, product creation, etc) should be given to somebody else ASAP. (Caveat: As a speaker you obviously have to deliver the speeches too). 

Don't be the cheapest provider in your market.

Define and document everything you do in your business. 

Someplace in some form you should have a "COMPANYNAME process manual". If you are not around your staff and/or spouse should be able to refer to this to know how to do everything you do. 

Invest a lot of money into your marketing.

Don't be cheap in this area. We'll spend $5 on coffee without missing a beat but wince on spending $29/month on something that brings new leads into your business.
