Of all you successful washers, how many became successful by learning on your own, and how many did it by doing this stuff for somebody else and then branched off and started up your own gig? How many had an education in small business and accouting, marketing as well as a good sales on top of all that?
I've been doing nothing but researching on top of researching and there is still so much to learn. Making time to go get hands on with somebody who is a professional already is a task in itself. I myself are one of those guys who accidently stumbled into the power washing industry. Ill admit $$$ signs made my Dad and I hungry to get a business going at first, but like anything else there's a heck of lot more to it then just going out and wash dirty stuff.
Keeping my full time job and doing small stuff on the side to learn is what I'm concentrating on. Eventually my goal is to do it full time though. It is enjoyable and rewarding when you can step back and know you did that work and it truely looks great. Even though I am new to the industry, ill throw in my little tip...a problem I've had is having my girlfriend want me home for this and that since I generally make my own schedule. Make sure your family, wife, husband, significant other or whoever is understanding to your commitment to your business. You owe it to yourself for taking the risk of investing your equipment. 7 days a week is often an only option whether its book keeping, finding more clients or doing the washing. I think people who fail sometimes get caught up in the "its my business" bubble and take off whenever they want and choose to spend their freetime in a non productive way. Expecially with a young business.
Best of luck!
