I've been struggling with this for a long time. I watch motivational videos of "what's your 'why'?" etc., and i still don't know.
I have "Time for a Change" written on a whiteboard in my office, and "goals" written below it. I have yet to write a single goal for 3 months because I have no idea.
I'll keep digging I guess.
In the blank about the 'blank slate' question, I would write "More excitement, spontaneous fun, and mandatory physical danger". I am wired to be that way.
