One Account, Zero Control

Most people run their entire financial life from a single checking account. Bills, savings, fun money — all swimming in the same pool. It's like tossing groceries, laundry, and dishes into one pile and hoping it sorts itself out.

When everything lives in one place, every dollar looks spendable. You check your balance, see $3,200, and feel rich — but $2,400 is already promised to bills and savings. Only $800 is actually yours to spend. That gap between the number you see and the money you have is the mental accounting problem, and it's why you feel broke right after payday.
