I'd go back to the early 1990s and I'd buy numerous domain names such as google.com, microsoft.com and so much more for next to nothing. I'd also go back a few years when
Bitcoin first stated and I'd invest when they cost virtually nothing, now making 1000s of times my initial investment.
It might not be time travel alone, but I wish I could go back and be 18 years old when I was just 13 years old in 1983 and it would have also been helpful if I had a brother with similar abilities to myself (unlike my 2 severely low functioning autistic brothers, don't get me wrong I love my brothers, but obviously they can't program computers when they literally are unable to count, I would want to keep my brothers as they are and have a 3rd able brother). From the early 1980s I was programming computer games, I sent some off to software companies, but always got back letters of rejection telling me to come back when I was older, but by then I'd missed the window of opportunity when computer games were simple enough for 1 person to potentially make a fortune by programming them. I did get a couple of games published when I was old enough at 18 and in the sixth form at school, but it was small time by then and I didn't make close to a fortune from it (I got into the local newspaper and I even made few thousand pounds overall from a 20% commission over a couple of years payable by monthly cheques, but sadly the computer was somewhat obsolete too by the time they were first published and sales slowly died off over time). David Darling and Richard Darling (brothers) however were from Birmingham in the UK just like myself and like myself they even started programming on the Commodore Pet in the late 1970s. Unlike myself however they were old enough in the 1980s to employed by
Mastertronic which was the first company to release budget priced home computer games and they soon made enough money to form their own company in 1986 which they called
Codemasters and yes it is the same huge game software company Codemasters as we know today (they're multimillionaires and were shortly after founding the company). It was also easier for them since there was 2 of them, so obviously they could work as a team supporting each other to get twice as much done. When I reached 17 I remember seeing them on the local news showing off their new found fortune, driving around in high end sports cars and it really p**sed me off. I always felt I'd missed out purely because I was too young when I was doing exactly the same stuff as them and back then I was most definitely equally as capable as either one of them, but too young and not legally employable or treated seriously because of my young age (back then they also didn't recognise that young children could program better than many adults, I could program complex code at the age of 10 for instance and probably would had done so even earlier if I'd been introduced to computers at a younger age still).
