<prompt> Human: Edit: For more clarification of what I am looking for, assume my investments are all top notch, debt is zero, retirement is well squared away, etc. My expenses, investments, and savings budgeting is done, but some money is still leftover, expected to be this way for years, even decades. My job is great, it is my hobby. What would you do with money that doesnt need to go anywhere? How do you handle it? Ive never had money that was discretionary, not for vacation, not for a new car, not even for a new suit. But I soon will and I have no idea what to do with that money when it happens. What rules and reasoning do you go through to decide I am in fact going to spend 30 to 30,000 on this thing.I grew up pretty poor like a lot of my fellow redditors, and Im in college now so everything that can be frugal is frugal, anything that isnt necessary isnt bought. Ive been doing pretty well, but I imagine when I am done and making 30k a year beyond my expenses I wont even know how to spend it. I dont want it all going into investments just so I can tell people I have a big retirement fund.What I am getting at here is that I know how to procure money, and I know how to make sure I have money when I cant procure it, but I dont know how to spend money. Do you set aside a percentage that you absolutely will spend within the monthyear? Break it up by hobby? Donations?What makes a purchase to you wasteful vs. valuable and what is your decision process to pulling the trigger or walking away? Right now, all purchases seem wasteful to me, even when I enjoy the purchase, and it always seems difficult to justify to myself that it is okay to do more than just have positive inflow of money.  <response>: -Does this make my life easier more simple?-Will this increase in value over time?-If I buy this, am I simply consuming?
