Honestly... 60 bucks on an obsession really isn't that bad, i spent like $5,000+ on my current obsession with dressing up so don't feel bad about it. Weather you earned that $60 as an allowance, working or just finding money laying about, it's your money, spend it as you please
But all seriousness don't beat yourself up for spending money on what you enjoy, Even if it's a lot of money, commitment on happiness is great! Hopefully it doesn't clutter up 😭
