I have a general question related to OP's situation: How do you make a resume look better when you have many short stints on it? I'm 30 and my average time to keep a job is less than 6 months. I always get overwhelmed and quit. When I start a new job I promise myself I will stick it out for just one year, but usually I'm white knuckling it within 3 months. I've been to doctors and therapists and have a clean bill of health. How do you develop grit and "sticktoitivness"?
