I basically didn't secure reliable, gainful employment until age 40. Prior to that I had, depending on how you count, two or three false starts at a career. But, I had become a hobbyist programmer in my early 30's. Briefly, in my late 30's I took a job as a software tester, but stayed only 9 months to give one last try at the career I was hoping for. When that didn't pan out and I finally had to rule it out, I returned to my software tester job. I was at the time a few months shy of my 41st birthday.

I stayed there 6 years, doing a tiny bit of programming professionally, and continuing to learn about programming as a hobbyist. I think I was 46 or 47 when I got my first programming job. I'm on my third now, and I'm 55.

I have been bitter, angry, and disillusioned—just like you. The only thing that helps is committing to something that will move you forward. Best of luck to you!
