I had this thought after remembering one time that my DT (digital technologies) teacher at high school suggested that some of the class could try join a hacking competition. Nothing ever came of it, but I thought it was interesting at the time.

What's really interesting is seeing the choices I made, and asking "what if I did the other thing". Just off the top of my head, I could be still at uni doing research on maths or physics, I could be working on designing new robots for who knows what, or branching off even earlier, I could have been a doctor like my parents.

I'm only 24, so it seems like I might be a bit young for this kind of thinking, but there's still a lot of things I could have done differently.
