Anyone have regrets/joys leaving a decent full time job for starting a business?

[MDLawn]

The title says it all. Just looking for other peoples experiences and decisions on the who what where when why & how of it. Were you kicking yourself for leaving, jumping for joy, making less or "rolling" in it, less stress to more stress or vice versa. I am however not making this into a judging thread but just curious to others experiences. I guess if I had to make it more specific I'd say that I would like to hear from more of the guys with the 30 week cutting season and not so much the year round southerners. But anyone feel free to comment.

And yes, it's on my mind regarding the title.....
