You are never too old to go back to school. I am living proof. I went back as a second semester freshman at age 43. I thought I wanted to be a pharmacist, but found my strengths lay elsewhere. I have now been an attorney for 12 years, and have been in government service with a passable salary that is three times what I made in radio and tv and benefits that broadcasting never provided for nearly nine of those years. I did it. You can do it. Visit the admissions office at the university nearest you and talk to a counselor. They can help you find the best path for you, and once you start, you can change paths as the goal becomes clearer.
