There are a few ways this seems to happen.
One you saw the layoff coming and began planning for this in the months or even years prior to losing the job.
Two you got laid off and went into planning mode and made your move while you still had plenty of unemployment left. In other words you picked your start time you didn't let poverty pick it for you.
Three you looking for other jobs and failed to find any your unemployment is gone and you say hey this looks easy ill give it a shot. This has the disadvantage of poor planning and the expected out come of one major mistake after another. But it does have one bright spot you got nothing to lose you have burned all the bridges behind you now failure will mean your life and thats a powerful motivator to most sane people.
I do like that this thread is coming out in February and not July and August. At the very least you got your timing right.
