You can grow your business as large as you like when you own it. The company's value is in the equity, which is total assets less total liabilities.Carrying debt costs money in interest expenses, so if you have any personal or business debt, eliminate that. When you are overburdened with debt, you can run into cash flow problems and bankruptcy issues. If you are carrying debt, be sure not to over leverage yourself or your business.
The bottom line is that it's not how much money you make that makes you rich; it's how you manage your money. You will increase your net worth when you use financial literacy skills for both business and personal finances. Net worth is how wealth is measured, so the higher your net worth, the richer you are.
