I had some advice given to me by a mentor years ago when I said I wanted to start my own business and that was “1) don’t do it 2) don’t do it and 3) don’t do it”.

Still I forged on.

The other advice I’d emphasise is that you are trying a new skill set. Typically you were working in a business, now you’re working on a business and the skills that made you great at the first in most cases aren’t present in the latter. So my advice is: cut through the rhetoric that “only losers quit” and “winners stay the course”… know your limitations and pull the pin if need be. I’ve done that myself and couldn’t be happier as I know my place now and no longer look over the fence at the greener grass. Now I know my grass is just fine the way it is!

Also, I have no regrets. I did it at a point in my life where I was in my 20s, had no mortgage and (most importantly) no children.
