For one thing, if you were born in 1893 instead of 1993, your early life would have been filled with much more fear of foreign threats. While many people in England worry about the effects of mass immigration into the UK today, there was much more reason to be worried about continental European geopolitics in the early 20th century. While some people denied that a great power war was possible in an age of so much economic interdependence (see Norman Angell's famous book The Great Illusion for an example of this thinking), other folks believed that a great big war was likely (see Bismarck's famous remark that a war would be brought about by "Some damnfoolish thing in the Balkans.") That kind of stuff might have dominated your teenage years if you'd been politically interested at that time.

Of course, at this age 100 years ago, you would have been in the British military fighting the Great War. Many of your best friends would have died or been seriously wounded in combat. Perhaps you would have shared their fate. If you were fortunate enough to survive, you would have had many encounters with the families of your deceased friends. It's difficult to capture the psychological impact that this would have on you as an individual, and the psychological impact that this had to the people and the nation that actually experienced this loss.

It's quite likely that your identity would have been much more centered on religion and nationalism than what it is today. There were certainly non-religious people of all sorts in the early 20th Century, but religion played a much more pronounced role in Western European society at that point than it does today, and it was much more bound up in temporal politics. Likewise, you likely would have taken much more pride in England's global domination than someone looking back at English history would today, where we're more prone to examine the many human rights abuses and indignities which colonized peoples suffered.

Obviously, the creature comforts you now enjoy would be radically different. No crisps, coca-cola, nor fruits in winter. Heating and air conditioning were not what they are today. And your entertainment options would have been much more limited as well. It's quite possible you could have gone for days at a time without hearing music, for example. Your best chance to hear it regularly if you weren't lucky enough to own a radio or record player would have been to go to church or practice in the choir.
