When I was younger (50ish now) I could juggle full time work with side projects but I just can't now, especially with family demands. Full time work is pretty much burning me out. I'm close to leaving and starting a mobile food cart.
When I do get out I'll definitely miss the salary. I'll miss lunch with the other devs. Miss the walks with other devs around the building. Theres something special about folks in engineering. When I'm serving up lunch and overhear some folks talking SDLC I'll smile and reminisce. But its not for me any more. I'm the gray hat now and have no desire to write code for someone elses fortune. Good luck getting out!
