I'm middle aged, I have a job I don't like that gives me no satisfaction, and that offers me no free time to pursue hobbies or spent quality time with friends or family.
A few months ago I started seriously considering a mid-life career change to gunsmithing.
After doing a lot of research, I determined that it would take a minimum investment of $20,000 and at least a year of full time study/practice.
At 45 years old and with a wife & a mortgage to support, I just don't see this as a possability.
I wish you luck in your endevor. For me, this will be just another dream that died.
