I think it is time to switch it up, feedback requested

I have been a service advisor for the last 8 years in all different brands in different sized dealerships. Started at Nissan when I was fresh into it, had a lot of money thrown in my face and it seemed too good to be true. Short story, it was. Left that dealer to pursue GM advising and have been with this brand for the last 6 years. I know I am not the only one who dreads going into work everyday to work 12 hour shifts and not bring home enough to put into savings. I want to switch up career paths and try something new but I actually have no idea where to start, what jobs to look for and where I would want to end up. I do have goals and aspirations for myself on where I want to be in 30 years but I know its going to be a long road to get there and I would like some sort of stability before I am able to pursue that. I am 26M and just looking to change to create a better life for myself and my family. Ever since I have been with GM, I will be the top performing advisor every single month pushing $140k per month in sales and still living paycheck to paycheck. Now I am at a very very large dealership with a presence all over the East coast and still nothing changes. There is no promotion from within the company and nobody seems to care that there is such a high turnover percentage in the advisor role. Would love some advice from any seasoned vets that have escaped the dealer grind and actually found something they are passionate about.

Thank you in advance for any help and knowledge.
