Path of life

So... it's been just over two years since I graduated with an Electrical Engineering degree. It has also been a little over two years since I've held my first REAL job (outside of internships, high school server experiences).

I've recently found myself in a rut. My career life seems a little dull and boring and completely UNCHALLENGING. The same stuff over and over again...
The idea of going back to school to get a grad degree in engineering is not appealing either.

... that's when I thought... MAYBE... I should go to medical school...

Any thoughts?
