Most of the challenges are when experiments don’t go as I expect them to. My experimental work involves a lot of different equipment (and live brain cells!) so it seems sometimes stuff doesn’t work together. However, when it does it’s completely incredible!
Being able to keep calm under pressure, slow yourself down, take a few deep breaths and think logically about what is going wrong really helps to overcome the problems… Or sometimes just admitting defeat and coming back the next day to try again.
