 
I'm not saying I'm right,  just saying how I am.  Drives my wife crazy sometimes.
I'm not opposed to spending money,  I just need to see the value in it, and tend to think big picture/ long term with my purchases.
Example: I dropped like $12K on home gym equipment a few years back, because the idea of how much I was spending for my wife and I's crossfit gym membership over several years was outrageous.
I think in general,  it's really easy to justify a $10 membership here,  a $20 membership there.  Then before you know it you're paying hundreds of dollars every month in memberships.
I'm probably just a crazy person like my wife says.......
