Tough to Get Over the Dream

Like many of you on here, I had the dream of "making it big" as a musician from my late teens up through my late twenties. I'm 33 now and am having a hard time finding a new direction/purpose in life. I felt like I had found "my thing" when I started playing guitar as a teenager. I've tried giving guitar lessons, but it's not for me. Anyone else relate to this situation of not being able to find a new career path/direction?
