Putting my wallet on a diet

OK, I've tried to be rational about this. I've gone through and cleaned out my wallet multiple times. I've taken out the membership card to the video store we never go to, Shira's old college ID, countless bits of paper, my dental card and whatever else I thought I could live without. My wallet was still bulging. It's gotten to the point where I find myself taking it out of my pocket when I sit in the car - that's not good.

So, I'm putting my wallet on a starvation diet. All it has in it right now are:

• A personal and business credit card
• ATM card
• Driver's License
• Some cash (remember I'm married, so we're not talking much here)
• A safety pin and a paper clip (which will both one day earn their own blog post, not doubt)

That's it. Finally, I can sit down again.

My plan is to add things back in as I find that I need them. Also, I'm thinking that I don't always need to carry around my medical card, I'll just bring it with me next time I go to the doctor. Same goes with my metro fare card - I'll just grab it the once every 3 months I actually use it.

I'm going to try my little experiment. If it goes well, I may try to pick up a money clip or smaller wallet to really complete the package.

So, tell me, how can this plan of mine backfire in the biggest possible way?

Update: So, Shira read about my plan. She doesn't approve. Specifically, she said that I should always have my medical card on me. Without it, the ambulance leaves you at the curb and the hospital won't let you in. I laid out my argument as to why this was most likely not true. I think it was a solid argument.

The medical card is now back in my wallet.
