I have a friend who I believe is also an ISTJ, or at least IXTJ, and he is exactly like this. He pinches pennies like crazy until he's set his mind on something he really wants. However, he doesn't usually talk himself out of it, unless he honestly thinks something better will be available soon.I'd like to think so. I save more than half of what I make per month unless I'm splurging on something like new computer parts or something to increase the enjoyability of gaming. I have expensive taste, but I'll usually think about buying something for so long that I'll talk myself out of it or tell myself I can't purchase it until I save up for a month or so.
I'm as exceptional with money as I want to be. If I have a goal in mind, then I can pinch a penny until you can see the tears in Lincoln's eyes. OTOH, I want what I want and I will do whatever is necessary to achieve that goal. I spend the extra money to buy only once, making sure I purchase what I really want.Is it true that a majority of ISTJ's are good to the point of exceptional when it comes to handling financial matters?
