Actually I did go back to school: I started my PhD in 2013, almost 20 years after I finished my undergraduate degree. It’s never too late to start again and I don’t really dwell on what I could or would have done better. Rather I try to learn from those mistakes and move on.
If I could go back to school though, I would tell myself to concentrate on maths and computer programming because they are the subjects that I still find the most difficult.
