I am a low voltage designer, I work and at a Mech/Elec engineering firm and it is an ok way to make a living but it won't be the dream you are dreaming.
Honestly I say stay in insurance and take the opportunities to advance. A friend of mine works insurance and got his own office. He hired some great people and they do 80% of his work and he comes in for the big clients. Other then that he is out hunting or fishing enjoying the world I only get to see through a window.
