Your brain objects and tells you going back to school and writing papers is too difficult for you. Reply, Mr. Voice, I understand how you FEEL about writing all those papers. Many others FELT exactly the same way when they went back to school. What they FOUND was because it was their choice to go back to school, and the subject was of their own choosing, they were capable and actually enjoyed writing papers.
Using FEEL, FELT, and FOUND is one way of breaking though your own thinking distortions. Many, many other people in your situation have succeeded in finding meaningful work, changing their lives, and so can you. Try using this technique to help you break through dysfunctional thinking barriers.
