I would go find soemthing new and exciting to do

a boring job takes up almost a third of your daily life.  does not worth whatever money they pay you. It seems you have a strong financial basis. going back to school should be fine if you know what can fulfill your needs. I have a feeling you can easily get bored about things that are routine. JD focusing on corporate acquisition may be something interesting. just a thought. you are the one who knows what you want. good luck!
