Turned 18 a month ago, thanks for making me feel old OP :D
I started with css, html, js and php when I was around 14/15 too.
You can afford your own .com website? I am jealous, I can only dream of owning such things.
I’ve always done it all for a hobby though, I’ve developed several systems, started out with MySql, now I hate it and prefer flat filing with .log text files.
##Edit: I am UK based, I forgot to add. I’m from Saaawwwffff London, you probably saw the burning buildings on the tv last Summer Time.
