How to make less money?

Take less shifts, get fired, take on more expenses, have kids, have a partner

Ask your boss for a lowering (opposite of a raise).

Talk to your personal banker. Tell him you want less money from your investment accounts every month. This will reduce your tax's. But gives you more growth in your accounts. To leave to some one when you die. You can also reduce the amount of rent you charge renters. Or find a bad renter to run up expenses on you.

Work less and play around more.

This is an IMPORTANT question gosh darnit! Stop moving it!

Being slow at work or less working

Wait. WHAT??!! Why would you want to make LESS money???

Ok, if that's your goal, maybe sign up for a Multi-Level-Marking scheme, especially one where you're required to pay for a starter kit. That should do the trick.

Of course, you could quit your current job and sell shoelaces door-to-door.

Spill coffee on the boss's shoes.
