Mines pretty corny in the eyes of most people, but I'd love to start up and run a successful PC business. Kind of on the scale of Origin PC's or something. I'd love to be able to have a decent sized warehouse and shop and build custom PC's and even build my own parts and sell them. I've taken a lot of inspiration from a well known guy here in Australia who owns and runs a company called Singularity Computers, he's got a very successful YouTube channel which he posts client build logs and recently got the chance to be able to make his own PC parts and brand them and sell them intentionally. He gets clients from all over the world and a build going anywhere near $25,000 isn't uncommon for him.
I know it's a pretty corny dream/ambition, but it's always been a goal of mine ever since I was a kid when I feel in love with computers and technology in general.
Another dream of mine would probably be to own a house and have it paid off before I'm 30.
