Even with multiple years in sales and out of the classroom it's really hard to compete against the resume folks with a business degree and getting their first start in a different industry working their way up. If you know someone that can get you an interview you will have an easier time making the switch. (Look at any Pharma rep or gas/oil industry reps and they want experience in that actual field).
Making less money than when I was teaching but still enough money for where I am in life with other perks that aren't salary but certainly lower my out of cost pocket like a company provided vehicle with gas card. Company covers all repairs up front so there is $0 out of pocket expenses for it.
Made the jump after a few decades in the classroom. Too old and don't care enough to compete with the hungry new grads trying to make a name for themselves and be aggressive sales folks. Too young to retire but knew I needed a change.
Still have busy seasons but not nearly as many evenings and virtually 0 weekends.
