How to stay creative while being an exhausted corporate drone

I have to admit, Im struggling to find the balance between a 40 hour work week, evening college classes, gym, cooking, cleaning, my dogs and my friends/man PLUS finding time to read/write/photograph/draw and just let my mind wander in order to spark those creative thoughts!

Any tips?

Im thinking that perhaps I need to set time to do NOTHING.....turn of all technology and go sit in nature or a quiet room with a pen and paper and see what happens..........
