You can do that for as long as you want. Ain't gunna do anything except tire you out. Eventually though you can accept the place you started in the river, and let the current take you down-stream. That's when you start living - when you accept the limitations of how you started in life and open yourself up to your own unique possibilities of your life adventure.
Also, my dad was 42 when he started university. He became a lawyer. Granted, university in my country was cheap at the time, and granted, he would be more comfortable now if he'd started earlier. But he made a good start, and it was better than sitting around and resigning himself to being unqualified.
On that note, I want to stress: it is never too late to re-qualify. And it's always worth it. Don't be embarrassed, don't come up with reasons why you'd never be successful - just go for it. Give it a shot. It'll work out in the end.
