I often have a really hard time with work-life balance. There always seems to be soo much to do in the lab that I rarely take a break. I often work at least 8 hrs a day & 6 days a week. There has been a good amount of research done showing that more work hours does not equate to more work accomplished but I have a hard time breaking my workaholic habit. When I do take a break, I read a book or watch a movie/series or go for a hike/mini-adventure around town (e.g. visit the art museum).
Sometimes I also draw as a way to 'escape.' When going into undergrad, I had the choice of pursuing art or science - and we see what decision I made. For a while I did some painting on the side and I still like to pull out a sketch pad once-in-a-while but my drawing sills have gotten quite rusty.
Starting in February, a group of PhD students at UQ banded together to start a Dungeons and Dragons group as an escape from our research - we are total nerds! The majority of players had never played an RPG game before, so we were all newbs together! Some of the best conversations have been when we have asked for extraneous ecology-related details, usually jokingly, that would be totally irrelevant to most players and may have irritated our DM a bit (e.g. 'what is the DBH of the tree I am trying to hide behind?' and 'what is the beta diversity of the forest we are walking through?').
I had a great time thinking up my character and developing my character's background. I might have enjoyed this a bit too much because I wrote (and am still writing) over a 5pg story for my character. And then I also felt the need to draw my character as well (for more drawing practice and because most pre-fab female fantasy drawings usually boast quite busty frames).
Overall, I think I have very poor work-life balance (I practically live on campus). I have been really pushing through, trying to finish counting seeds (PROGRESS REPORT: 397,101 seeds from 7,667 envelopes - about halfway done). But I am working hard to schedule some down time for myself including D&D games, evenings where I work reading a fantasy/sci-fi book, and small trips to the local museums (which there is an awesome MARVEL exhibit coming soon).
