I'd like to take my life back a decade, to 1999, when I was 11 years old. In 1999 I finished primary school and of course you have to go through the decision of what secondary school to attend.
I'd choose what was then my second choice. Not to say the choice I did make was wrong, it's just in hindsight I don't think it was the best one. I recently read up on the Butterfly effect (no not the film, the actual theory) and I believe this is the small change that would drastically change my life for the better. Again, not to say I currently have, or have had a bad life, I just think it could be a lot better.
I went through secondary school with a small circle of friends, some really good ones though, though we are no longer in contact aside from being friends on Facebook. The only downside to not taking that choice is never meeting them, but I believe if I went to my second choice of school, I would have had a much larger circle of friends, a circle that would actually include girls this time. I'd have a lot more confidence and would have made different decisions on subjects to take for my A levels, which in turn would cause me to probably choose a different subject to study at university.
Good thing about this choice is that in all likelihood, I'd still create a website called The GTA Place 2 years later. By 11 I was already heavily into computers and videogames, I'd been around them and even using them since I was just 4 or 5 years old (thanks Dad!), yeah, that young, Windows 3.11 for Workgroups FTW! So yeah chances are I still would have picked up the GTA games. The friend who first let me play GTA3 on his PS2 I've known since I was born, so that wouldn't have changed.
So you see, I'd still have all the nice things I like about my life now, but additionally I'd have a lot more friends, probably even a girlfriend, probably have a better career path ahead of me too, rather than the shitty one I have right now. All that changed was my choice of secondary school. That's why I'd like to go back to 1999 and replay that year, so I could make that choice.
I think my answer was deeper than anyone else in this topic, so yay for me!
