Interesting situation. You certainly have FU money, so don't feel pressured to return to slavery right away. On the other hand, when unemployment runs out -I have no idea of your stance on paying for kid's college, medical insurance, or viability of changing career / being an entrepreneur...
You mention starting online income - realize right away that it's a lot different than having an employer with defined benefits. Sometimes I think it is overly glamorized, which JD Roth and MMM can do because already 'won the lotto' with their websites. Not so much for the guys and gals that 'come in second'. And even for the winners, it took time and hard work before they hit critical mass. You have to be willing to put in years of effort making less than minimum wage... The only immediate upside is that it also helps keeps your expenses lower, since you are focused on a goal as opposed to looking for something 'fun to fill the time'. Blogging is addictive, especially when things go your way, but money doesn't immediately follow like other mainstream 'jobs'. There is no 'commission' for a big sale, just the hope for a steady build as long as you can maintain momentum.
Hope some of that helped, I'm excited to hear your journey and decisions and participate where I can help out. I might get laid off this year or next too.
