I am finally getting out, getting out of a job I sometimes hate so intensely that I can't bring myself to get up in the morning. The new job is great, on the outside. Great manager, opportunity to work from home, everything that I need in my life right now. But I'm terrified. Terrified that another year of office life will kill me, that I with everything else being perfect I will stay hate my job. Then what do I do, I can't blame it on my horrible manager, or my lack of exciting work. Then the problem becomes me. What do I do then?
