<prompt> Human: I dont consider myself an impulse buyer. Everything I want is usually well thought out and necessary to my life, but today I made a purchase thats both expensive and I could live without.I spent 2K on PC parts to do a custom build. Purely recreational fun. I kept convincing myself I didnt need it, but my bank account currently has 16K in it and i just invested 5,500 into my Roth IRA to end the fiscal year.With that being said, does anyone else feel like absolute SHIT when they do something like this? Like, why am I doing that? Its something Ive thought about for months, but making all these 200-600 purchases on my credit card for some reason makes me feel sick.Can anyone give me some insight on what Im experiencing?Assistant: You like saving money and being thrifty. Thats fine. Its also fine to treat yourself occasionally, if you can afford it.2k is a lot if youre not used to spending that kind of money. But dont look at the purchase amount on the CC. Instead, look at your paychecks, your bank account, and your investments to see if you can afford it.Human: How do you determine if you can afford something? Honest question.I make 1,310 net biweekly, but pay very little expenses since I live with my parents. Have 10.5K in an IRA, 16.5K in savings, and about 14K in college loans at 3.4.At what point do you determine you can afford something?  <response>: I make quite a bit of money, and even after spending 1000 on something, I will always question rather I really needed it or not. Im a compulsive saver and love investing money, so spending money on something always feels wrong, even when I can easily afford it.Every so often, when I have been wanting something for awhile, I make myself get it. I never regret it in the long run, but I always do for about a week.
