Ken,
Google Small Business
Google the percentage of successful small businesses that make it in today's economy.
After doing the research, ask yourself if you can take the risk of quitting your job (assuming you have one as opposed to being retired, disabled, etc.) and making a go at whatever it is you feel you could do, production or retail wise, to make a living.
If you feel you can, you should have no problem paying your mortgage, utilities, food, gas, etc.
If you become successful you
then have a right to tell people how to run a business.
Best of luck.
Also Google "Master Craftsmen"........... a whole new level of success only few can achieve.
