A lot of truth in the replies.
Your love of the hobby will not help you succeed. Working your ass off will help you succeed. Steady customer traffic will help. Keeping up on payroll (not your own), lease payment, cam fees, utilities, employee taxes, sales taxes, distributor bills, silly town/county/state fees...will help.
I haven't seen a 48 hour work week in 8 years. 60+ is the norm. Your employees are not invested in your business. Most will just want to collect a paycheck.
Do I want to go back to working for someone else? Hell no! But it's no cake walk.
