You're 16 which is fine. Nothing wrong with that age except time appears to go too slowly and you have no money. (No different to 40 except time goes very quickly!!)
While school may bore you to tears I'd really seriously think about staying on or at least applying yourself to get the best grades you can. At the moment it may not seem relevant but in 2 years time you'll be pleased you have got them. You don't need a degree to fly so don't worry about uni per se. However, decent GCSEs and a couple of A levels will help you in the long run.
At the moment you say that you're not interested in money or a big house. To be brutally honest, you'll be flat out buying a mid sized house on a jet captains wage in the SE of England so the big house thing is safe.... However, there will become a time when you'll want a decent livable wage. If you crack a position as a full time instructor for the "big" flying schools then you'll probably earn a civilised pay but if you don't, you'll be flat out paying rent. At 16, who cares? At 26, hey, life's great-ish. At 36? You'll really care.
Flying isn't about zooming around the big sky going "weeeeeeeee". It is a highly disciplined occupation that relies heavily on SOPs, rules and the following of them. I doubt there's a more scrutinised and checked industry.
Any way, I like it. Nothing wrong with dreaming, but get your foundations solid.
