I am considering your request of doing a hub on this issue. But in a nutshell, I love tutoring kids and, like you, I like being self-employed. Yes, psychology is fascinating. I bring a lot of what I learned in that field to my work with children. Did you read my hub on comparative psychology (parrot intelligence)? I read yours on self-employment & plan to read more. I hope to publish more hubs on psychology, teaching, human rights, and other issues.
