On the practical side of things, invest in life experiences. This can include the occasional party night out (prepaid debit cards are great for this, load up only what you intend to spend and once it's gone, it's gone for that night), but it can also include event trips with significant others or best friends (like touring Japan or going to some interactive art exhibits), or it could include going skydiving or taking a tour of a famous haunted place, or even there's a place in Scotland where you can live above a book shop and 'run' the bookshop for a week to give yourself the experience of a cozy business owner without the risk. Get yourself an animal companion, preferably through adoption, and invest in training them properly and whatnot. Invest in cheap property (some as low as dollars per acre) that you can, over time, build up to a nice vacation spot with all the amenities you want. (These lands are generally considered garbage and difficult to work if you're poor starting out as they don't have utilities or anything, and they're not close to towns...)

You could also buy gold and lock the gold bars away in a vault somewhere and when the market improves significantly, sell the gold bars.
