In that case you are well placed to give it a shot. There are few certainties in life, but you are not in a bad position. A few months ago I was in the same position as you, was procrastinating about quitting, and ended up getting made redundant as a complete suprise. Personally I haven't looked back. Nothing is guaranteed, you need to personally decide more which you will regret most: quitting now, taking the risk and going for it, or waiting till till later when the economy might be better, but then you're personal circumstances might have changed. At the end of the day - it has to be your decision, but if you do genuinely have 3-4 years of cash, then go for it!
