Hey, what a useful exercise! It's great that your hours allowed you to dip your toe in the water of something new without having to give up the 'real' job. Doing the office job for that short while has renewed your commitment and motivation. I used to find that when visiting various hospitals - if they were bad I came back thinking how lucky I was - if they were good I came back with fresh ideas. Win-win. I'm happy that you have had the time to reflect and conclude what matters to you.
