If not self-employed, immediately take a leave of absence. Expect not to return. You won't have to quit your job. Your pre-jackpot job will, most likely, quit you.

Fellow employees may try to make you feel guilty for keeping your job from some other person perceived as more needy. Co-workers can become jealous and resentful. Supervisors assume that you will quit eventually, so your promotion is unlikely and your responsibilities may become increasingly limited.
