1) Reason with him - if he concedes to your wishes you will let him live.

2) Appeal to his intelligence - tell him he has some.

3) Teach him - 'This is how to love me', 'this is what I need'.

4) Make him feel good - pretend you agree with something he said.

5) Collect a debt - He must 'owe you' for something he did - or didn't do.

6) Even things out. He bought something - now it's your turn.

7) Cash in a future obligation. Your anniversary is coming again isn't it?

8) Bribe him - just tell him you'll change.

9) Lie to him - tell him he's not really an idiot.

10) Threaten him - then follow thru.

11) Cry wolf - then just cry.

12) Trade him - whatever you can think of.

13) Summarize your feelings - 'Without this walk in closet  I'll never be happy again'.

14) Torture him - with the quiet treatment.

14) (Alternate)  Torture him - never stop talking.

15) Do the take away. Start with this word - 'Fine'..and then start taking.

16) Reason with him - If he buys the luxury closet system you won't make him buy a boat.

17) Beg - You must deserve this...think of a reason.

18) Borrow - borrow this line from me, 'It's not a luxury, it's a necessity.'

19) Steal - Use his credit card instead of your own for the luxury closets.

20) Over rule him. If all else fails, just overrule him and be done with it.
 
That's enough - that should do it. And don't tell him where you learned  this stuff.
