After four tries, I think it might be time to try something else. Try reading What Color is Your Parachute, or finding a library and asking if they have any tests you can take that help you find the right career for you. Or just get a job, any job, and see if you like it.
Someone close to me wanted to be an aerospace engineer. He’d always dreamed of it since he was a child. He failed out of the program, and graduated in physics (which was less rigorous at his college), with a very mediocre GPA. He was very discouraged about his career prospects, and got a job at a temp agency to earn some money. He started to get involved with improving their internal computer systems. One promotion led to another, and finally to another company, where he’s a Director of their online sales and makes a comfortably 6-figure income. It turns out that his good but not great technical skills, combined with his management skills, were a good recipe for success. Imagine if instead, he’d kept chasing the dream of becoming an engineer, even though he wasn’t good at it.
