> Paying your mortgage feels more urgent than contributing to a brokerage account
Of course it does, because if you spend your monthly brokerage allowance on a fancy dinner and booze, nothing too bad will happen. If you spend your mortgage payment on booze and steaks, you lose your house.
That's not a "mind trick", that's a real problem with serious repercussions. Housing is not just an investment for most people, it's THE investment, with life-changing, family destroying consequences if you don't keep it afloat.
