What are you going to do with your life z?

I got into law school in 2001. By 2002 I was expelled for low grades. After that I was diagnosed as learning disabled because of a childhood brain injury. I spent 2002 trying to get back into school but couldn't and since then I have been feeling adrift, moving from one continent/profession/job to another. At about 5 months, this job will be the longest lasting one. (Assuming I am fired on October 4, when the new term begins.) I know I can get another job, and another and another ad infinitum but don't see it adding up to something of substance, to an accomplishment to call my own. I don't like feeling adrift.
