It's a risky thing, borrowing money to start or buy into a business. Borrowing for edumacation, too. Supposedly I make a good living, but I still have to watch money, in actuality my primary paycheck goes to bills.
94% of my after-tax paycheck pays my mortgage (with insurance and taxes in escrow) plus my student loans and business loans.
You and your industry is the perfect example. Most people see the income and not the liabilities. Most do not see the blood, sweat and tears you have invested in the future. Or the time and the amount of dollars it has taken for you to get to where you are at. Those folks will never understand or appreciate the effort or time, but they sure do have an opinion about it.
