What to spend my money on?

I'm a 15 year old boy and was given £180 for my birthday and I already had £130.

So far I have £150 remaining, I have spent the money so far on a new CPU Cooler for my desktop PC, some FIFA 14 coins (500k) and money for my own minecraft server to help it stay running for 5 months 24/7!

I'm now stuck on what I should buy, I don't want to waste the money on something I'm never going to use but then again I don't want to save the money either. Any ideas would be appreciated. Thanks also I have a job and that is why I don't want to save, I owe my parents some money and money from my job is going towards paying them back, I guess I could give them some of this money but I want to buy something for myself as this was my birthday money!

I think you are looking at this backwards. It seems you just want to spend the money rather than that there's something you really want and are wondering if you can afford it. What you spent so far was done correctly. Wait until there's something that you really want, then you will be thrilled to able to buy it. Calling this "saving" takes the fun out of it. Think of it as being prepared for an opportunity to get what you want when you want it.
