Why do I keep failing at everything?

Everything I ever do I'm bad at. I always fail at every single thing no matter how much time I put into it. I can't draw, paint, sculpt, 3d Model, read/write. I'm terrible at playing video games, I'm terrible at cooking. I can't go 5 seconds without constantly forgetting somthing and doing everything half way before getting distracted. It's cost me a lot of jobs. I've had 14 jobs in the past 4.5 years. I can't rockclimbing, snow board, skate. I can't ever get good at pottery, or blacksmithing. I'm trying Every single thing that has to do with making things cause I have all these ideas rushing though my head of what i want to paint, draw, model, sculpt, write about. I have all these ideas just rushing and spilling out but it keeps spilling out like crap and I don't know what to do. I've easily spent thousands of hours in many of these and yet im still a failure and never good enough. I get so frustrated I self sabotage myself and anything I see as my failure. I fail friends, I've failed my family and they have made sure I remember that. I'm going into welding, hoping I don't fail at this too.
